15 best caves in the UK to visit

Britain's most impressive caves reveal landscapes that are largely invisible from the surface.

Beneath the Yorkshire Dales, Peak District, Mendip Hills and Bannau Brycheiniog lie chambers, underground rivers and passageways shaped over immense periods by water moving through limestone. On the north coast of Scotland, Smoo Cave combines sea erosion with a freshwater stream, while Marble Arch Caves in County Fermanagh introduces visitors to one of the most active river-cave environments open to the public in the UK.

The best cave visits are not necessarily the deepest or longest. A successful show cave needs safe access, thoughtful lighting and interpretation that explains the geology without overwhelming the space. Some attractions provide guided tours through narrow passages and large chambers. Others are self-guided, allowing visitors to move at their own pace. A small number depend heavily on rainfall, tides or sea conditions.

Caves also contain human stories. Kents Cavern has evidence connected with prehistoric occupation, while Gough's Cave at Cheddar is associated with important archaeological discoveries. Chislehurst Caves are largely human-made rather than natural, but their long history of excavation, industry, shelter and performance makes them one of Britain's most distinctive underground visits.

This guide brings together 15 of the best caves in the UK to visit. It covers major show caves, prehistoric caverns, river systems and coastal caves across England, Wales, Scotland and Northern Ireland.

Cave conditions can change quickly. Flooding, high river levels, maintenance, rock movement and severe weather may affect access. Check current opening and tour information before making a special journey.

How we selected the best UK caves

Our editorial assessment considered:

• Geological interest: Chambers, formations, rivers, faults and the story of how the cave developed.
• Quality of the visit: Tour structure, lighting, interpretation and time underground.
• Scale and atmosphere: Whether the cave provides a genuinely memorable underground environment.
• Historical significance: Archaeology, folklore, mining or human use where relevant.
• Natural integrity: Presentation that supports rather than overwhelms the cave.
• Accessibility: Steps, narrow passages, gradients and published visitor information.
• Family suitability: Whether children can engage safely and meaningfully.
• Sense of place: A strong connection with the surrounding gorge, coast, mountain or limestone landscape.
• Value: Whether the cave and wider attraction justify admission and travel costs.
• Geographical balance: Strong choices from England, Wales, Scotland and Northern Ireland.

Caves in Somerset and south-west England

1. Gough's Cave at Cheddar Gorge, Somerset

Website

Location: Cheddar, Somerset

Visit format: Self-guided show cave within the Cheddar Gorge attraction

Best for: A complete combination of major cave, archaeology and dramatic surface landscape

Gough's Cave extends beneath the limestone cliffs of Cheddar Gorge and provides one of the most complete cave visits in Britain.

The public route passes through large chambers, stalactites, stalagmites and rock formations created by water moving through the Mendip limestone. Lighting is designed to reveal the scale and structure of the cave, while interpretation connects the underground landscape with the gorge outside.

The cave also has exceptional archaeological importance. Cheddar Man, one of Britain's best-known ancient human remains, was discovered here, and other finds have contributed to the study of prehistoric life and mortuary practice.

A standard attraction ticket commonly includes more than the cave alone, with access to the gorge walk, museum displays and other visitor elements under current arrangements. This makes Cheddar stronger as a full day than as a single underground tour.

Why it stands out:

Gough's Cave offers the UK's best overall combination of accessible cave scenery, prehistoric archaeology and an extraordinary landscape above ground.

Good to know:

Cheddar becomes extremely busy during warm weekends and school holidays. The cave is easier than some guided systems, but visitors should still expect steps, damp surfaces and cool temperatures.

2. Wookey Hole Caves, Somerset

Website

Location: Wookey Hole, near Wells

Visit format: Guided and attraction-led cave experience, depending on the current ticket

Best for: Families wanting caves alongside a large indoor and outdoor attraction

Wookey Hole is one of Britain's most famous cave attractions and has a history shaped by geology, archaeology, folklore and tourism.

The River Axe flows through the cave system, creating chambers and passages beneath the Mendip Hills. The public route reveals sections of this active environment alongside formations and the long-standing legend of the Witch of Wookey Hole.

The attraction extends far beyond the natural caves. Family entertainment, historic paper-making displays and seasonal activities form part of the wider visit. This breadth is useful in poor weather and for younger children, although visitors seeking an undisturbed geological experience may prefer a more focused show cave.

Wookey Hole has also developed additional guided experiences, so current tour descriptions should be read carefully before booking.

Why it stands out:

Wookey Hole provides the broadest cave-based family attraction in the UK and remains an important part of the Mendips' visitor history.

Good to know:

The complete attraction can feel busy and commercial. Confirm which cave route and experiences are included in the selected ticket.

3. Kents Cavern, Torquay

Website

Location: Torquay, Devon

Visit format: Guided cave tour

Best for: Prehistoric archaeology and an accessible introduction to cave history

Kents Cavern is one of the most important prehistoric cave sites in Britain.

The limestone chambers have produced evidence associated with early human occupation and Ice Age animals. Archaeological discoveries have helped researchers understand a period when humans, mammoths, cave bears, hyenas and other species occupied or moved through the wider landscape.

Guided tours combine geology with these human and animal stories. The cave is substantial enough to feel atmospheric but generally more manageable than the longest and most physically demanding show-cave tours.

Its location within Torquay also makes it easy to incorporate into a South Devon holiday, particularly when beach weather fails.

Why it stands out:

Kents Cavern provides the strongest visitor experience for understanding the relationship between British caves, early humans and Ice Age wildlife.

Good to know:

Tours run at set times and can fill during holidays. The cave remains cool throughout the year, even when Torquay is warm.

Caves in Yorkshire and northern England

4. White Scar Cave, Yorkshire Dales

Website

Location: Near Ingleton, North Yorkshire

Visit format: Guided tour

Best for: The longest show-cave tour in Britain and a genuinely substantial underground walk

White Scar Cave lies beneath Ingleborough in the Yorkshire Dales National Park.

The guided route covers approximately one mile and takes around 80 minutes. Visitors pass an underground waterfall, narrow passages and large chambers before reaching the Battlefield Cavern, whose scale provides the tour's most dramatic moment.

The journey feels more adventurous than many family show caves because parts of the route are low or confined. Hard hats are provided, and the walking distance is significant enough that visitors should treat it as a physical activity rather than a passive attraction.

The cave's setting near Ingleton makes it easy to combine with the waterfall trail, Ribblehead or a wider exploration of the limestone Dales.

Why it stands out:

White Scar provides the UK's most substantial conventional show-cave tour and one of its strongest senses of travelling deep into a real cave system.

Good to know:

The tour is unsuitable for anyone unable to bend through lower sections or manage numerous steps. Wear practical footwear and arrive before the scheduled tour time.

5. Ingleborough Cave, Yorkshire Dales

Website

Location: Clapham, North Yorkshire

Visit format: Guided show-cave tour reached by a woodland and gorge walk

Best for: Combining an attractive approach walk with an accessible show cave

Ingleborough Cave is reached from the village of Clapham through the Ingleborough Estate Nature Trail.

That approach is central to the experience. The path follows woodland and the valley towards the limestone landscape beneath Ingleborough, allowing the cave to feel like a destination discovered on foot rather than a roadside attraction.

Inside, the guided route reveals flowstone, stalactites, stalagmites and formations developed through a cave system linked with the wider Gaping Gill area.

The public cave tour is more approachable than technical caving but still contains steps, damp surfaces and confined sections.

Why it stands out:

Ingleborough Cave offers the most satisfying combination of surface walk, limestone scenery and traditional guided cave tour in England.

Good to know:

Admission to the cave and access through the estate trail may involve separate or combined arrangements. Allow enough time for the walk in both directions.

6. Stump Cross Caverns, Yorkshire Dales

Website

Location: Greenhow Hill, near Pateley Bridge

Visit format: Self-guided show cave

Best for: Exploring at your own pace and combining caves with Nidderdale

Stump Cross Caverns lie beneath the high ground between Wharfedale and Nidderdale.

The cave system was discovered through lead-mining activity, and the visitor route passes through chambers containing stalactites, stalagmites and flowstone. The self-guided format gives families more control over pace than a fixed group tour.

Interpretation explains the geology and discovery of the system, while the visitor centre provides food and shelter in an exposed upland location.

Stump Cross is smaller in public-route scale than White Scar, but the ability to move independently makes it suitable for visitors who dislike staying with a large tour group.

Why it stands out:

Stump Cross provides the best self-paced show-cave visit in the Yorkshire Dales and combines naturally with a broader Nidderdale journey.

Good to know:

The site sits on high, exposed ground where weather can differ from nearby valleys. Check opening and road conditions during winter.

Caves in the Peak District

7. Peak Cavern, Castleton

Website

Location: Castleton, Derbyshire

Visit format: Guided walking tour

Best for: A vast natural entrance and the relationship between caves and village history

Peak Cavern has one of the largest natural cave entrances in Britain.

The entrance chamber sits immediately behind Castleton beneath the ruins of Peveril Castle, creating an exceptional relationship between village, gorge and underground space. Historically, rope makers worked within the shelter of the cavern, and this human use forms an important part of the guided visit.

The tour continues into passages and chambers shaped by the Peak District's limestone geology. Compared with heavily decorated show caves, Peak Cavern's appeal lies more in scale, atmosphere and social history.

It also hosts occasional concerts and events, using the acoustics and size of the entrance chamber.

Why it stands out:

Peak Cavern offers Britain's most impressive natural cave entrance and one of the strongest connections between a cave and the settlement outside it.

Good to know:

The route involves uneven ground and low sections. Event access differs from ordinary guided tours.

8. Speedwell Cavern, Castleton

Website

Location: Winnats Pass, Castleton

Visit format: Guided underground boat journey and walking tour

Best for: Britain's most memorable underground boat experience

Speedwell Cavern is entered through a long flight of steps leading to an underground canal.

Visitors board a small boat and travel through a narrow passage originally excavated as part of an unsuccessful lead-mining venture. The confined journey creates a strong sense of entering deep underground before the tour reaches the larger cavern beyond.

Speedwell is partly a mine passage rather than an entirely natural show cave. That combination is the point: the attraction demonstrates how human excavation intersected with the natural cave system beneath the Peak District.

The boat journey distinguishes it from every other cave in this guide, but the confined environment will not suit all visitors.

Why it stands out:

Speedwell offers the UK's most distinctive underground boat tour and a memorable introduction to the Peak District's mining and cave landscape.

Good to know:

There are many steps, low headroom and tight spaces. Visitors uncomfortable with confinement should choose Peak Cavern or Treak Cliff instead.

9. Treak Cliff Cavern, Castleton

Website

Location: Castleton, Derbyshire

Visit format: Self-guided audio tour

Best for: Blue John stone and detailed mineral formations

Treak Cliff Cavern is one of only two places associated with the extraction of Blue John, the rare coloured fluorite for which Castleton is famous.

The cave contains natural chambers, stalactites and mineral deposits alongside areas shaped by historic mining. Blue John veins provide the defining feature, connecting the cave to local jewellery, ornament-making and industrial history.

A self-guided audio tour allows visitors to move through the route independently. This is particularly useful for families who need breaks, though everyone must still manage steps and uneven cave surfaces.

Why it stands out:

Treak Cliff offers the best complete visitor experience for understanding Blue John stone within the cave where it occurs.

Good to know:

The site is reached uphill from Castleton and includes numerous steps. Check current tour format and Blue John workshop availability.

10. Blue John Cavern, Castleton

Website

Location: Winnats Pass, Castleton

Visit format: Guided cave tour

Best for: Historic Blue John mining and a more traditional Castleton cavern tour

Blue John Cavern occupies the hillside above Castleton and remains connected with the extraction of Blue John stone.

The guided tour descends through chambers and passages where geology and mining history overlap. Visitors can see mineral veins, cave formations and evidence of the work required to recover a fragile decorative stone from difficult underground conditions.

The route is more physically demanding than its proximity to the road may suggest, with a large number of steps on the return climb.

Why it stands out:

Blue John Cavern provides the most traditional guided explanation of active Blue John mining and its place in Castleton's identity.

Good to know:

Be prepared for a lengthy stair descent and ascent. Treak Cliff may suit visitors who prefer a self-guided format.

Caves in Wales

11. Dan-yr-Ogof and the National Showcaves Centre for Wales

Website

Location: Pen-y-cae, Bannau Brycheiniog

Visit format: Self-guided show caves within a large family attraction

Best for: The most extensive complete show-cave attraction in Wales

Dan-yr-Ogof forms the centrepiece of the National Showcaves Centre for Wales.

The public experience includes Dan-yr-Ogof itself, Cathedral Cave and Bone Cave. Visitors encounter passageways, underground lakes, formations and a dramatic cavern where water descends through the rock.

Only part of the much larger cave system is open to general visitors. Exploration beyond the show-cave route is reserved for properly equipped and authorised cavers.

The wider attraction includes dinosaur models, farm animals, play and historical displays. As at Wookey Hole, this broad family offer can feel very different from a quiet specialist cave, but it makes the site capable of filling most of a day.

Why it stands out:

Dan-yr-Ogof provides Wales's most substantial and varied public cave attraction, with three contrasting underground experiences in one visit.

Good to know:

The attraction operates seasonally and uses dated admission. Check the 2026 calendar before travelling outside school holidays or summer.

12. Sygun Copper Mine, Gwynedd

Website

Location: Beddgelert, Eryri

Visit format: Self-guided underground mine and cavern route

Best for: Mineral colour, mining history and an atmospheric underground visit in Eryri

Sygun is primarily a historic copper mine rather than a purely natural cave, but its underground route passes through rock formations and mineral-rich chambers that make it one of Wales's most rewarding subterranean visits.

The self-guided tour follows tunnels and workings associated with nineteenth-century copper extraction. Audio interpretation explains the miners' conditions, tools and methods, while the visible mineral staining gives the underground spaces unusual colour.

Its location near Beddgelert makes Sygun particularly easy to combine with one of Eryri's most attractive villages and surrounding walks.

Why it stands out:

Sygun provides the strongest combination of underground mineral scenery, mining history and a beautiful national-park setting.

Good to know:

The route contains steep steps and uneven surfaces. It is included as an underground cavern experience, but visitors seeking an entirely natural cave should prioritise Dan-yr-Ogof.

Caves in Scotland

13. Smoo Cave, Sutherland

Website

Location: Durness, Sutherland

Visit format: Free public access to the main chamber, with optional guided deeper tours

Best for: A dramatic coastal cave shaped by both sea and freshwater

Smoo Cave lies beside the north coast near Durness and has one of the most extraordinary entrances of any cave in Britain.

The outer chamber was formed through marine erosion, while a freshwater stream descends into the cave through an inland sink system. This combination creates a sequence of spaces shaped by two different processes.

A walkway allows free access to the waterfall chamber under normal conditions. Guided tours venture farther into the system when river levels and weather permit.

The cave's setting on the North Coast 500 route makes it popular, but it should not be treated as a casual roadside stop in severe weather. Water levels can change quickly and tours may be cancelled.

Why it stands out:

Smoo is Scotland's most dramatic accessible cave and one of the UK's clearest examples of sea and freshwater erosion meeting in one site.

Good to know:

Public access to the main chamber is normally available throughout the year, but deeper tours depend on safe conditions. Wear footwear suitable for wet steps and paths.

14. Fingal's Cave, Isle of Staffa

Website

Location: Staffa, Inner Hebrides

Visit format: Boat trip and weather-dependent island landing

Best for: Basalt columns, Atlantic scenery and one of Britain's great natural landmarks

Fingal's Cave is a sea cave formed within the remarkable basalt columns of Staffa.

Its geometric walls are related geologically to the formations at the Giant's Causeway in Northern Ireland. Waves entering the cavern create powerful echoes, helping inspire the cave's long association with music, poetry and Romantic travel.

The experience begins well before the cave itself. Boat journeys from Mull, Iona and other departure points cross exposed water and approach Staffa's dark cliffs before landing where conditions allow.

Access along the path beside the cave is weather-dependent and may be slippery or exposed. Some trips can view Staffa from the boat without guaranteeing a landing.

Why it stands out:

Fingal's Cave is the UK's most visually extraordinary sea cave and one of the world's great basalt landscapes.

Good to know:

A landing is never guaranteed. Sea conditions, mobility and slippery paths make this unsuitable for some visitors, and the cave should not be entered during unsafe conditions.

Caves in Northern Ireland

15. Marble Arch Caves, County Fermanagh

Website

Location: Florencecourt, near Enniskillen

Visit format: Guided walking cave tour, with access affected by water levels

Best for: Underground rivers and the finest guided cave experience in Northern Ireland

Marble Arch Caves lie beneath the limestone hills of County Fermanagh within the Cuilcagh Lakelands UNESCO Global Geopark.

The system contains subterranean rivers, chambers, waterfalls and formations shaped by active water movement. Guided tours explain how streams disappear underground and combine within the cave before eventually returning to the surface.

Historically, parts of the visitor experience have involved a short underground boat section when water conditions allow. Current tour formats can change according to river levels, so the official description should be checked rather than assuming that a boat ride is guaranteed.

The surrounding geopark adds considerable value, with limestone landscapes, walking routes and the nearby Cuilcagh area supporting a complete day or short break.

Why it stands out:

Marble Arch Caves provides Northern Ireland's finest public cave experience and the UK's strongest accessible example of an active underground river system.

Good to know:

Tours can be altered or cancelled after heavy rain. Advance booking is strongly recommended, and visitors should arrive prepared for cool, damp conditions.

• Spar Cave on Skye, approached only with tidal knowledge
• Caves around the Antrim coast reached through guided kayaking
• Pollnagollum Cave viewpoints in County Fermanagh
• Crag Cave and Aillwee Cave in the Republic of Ireland for travellers extending the trip beyond the UK

Several are mines, shelters or adventure-caving sites rather than managed show caves. Access should never be assumed.

Best caves for different visitors

Best overall cave visit

Gough's Cave at Cheddar provides the strongest combination of cave scenery, archaeology and an exceptional surface landscape.

Best long guided cave tour

White Scar Cave offers the UK's longest conventional show-cave tour and a real sense of underground travel.

Best cave for families

Dan-yr-Ogof provides the broadest complete family day. Wookey Hole is the leading English alternative.

Best cave for prehistoric history

Kents Cavern is the strongest focused visitor experience, while Gough's Cave has exceptional archaeological significance.

Best underground boat journey

Speedwell Cavern provides the most dependable dedicated boat-tour format. Marble Arch may include water-based elements depending on current conditions.

Best cave in Wales

Dan-yr-Ogof is the country's leading natural show-cave attraction. Sygun is better for combining underground exploration with mining history.

Best cave in Scotland

Smoo Cave is the most accessible and dramatic mainland choice. Fingal's Cave is the greater natural spectacle but requires a boat journey and suitable sea conditions.

Best cave in Northern Ireland

Marble Arch Caves is the clear leading choice and one of the UK's most important underground river attractions.

Best for independent exploration

Stump Cross and Treak Cliff offer self-guided routes, subject to the attraction's current format.

Best for geology enthusiasts

White Scar, Dan-yr-Ogof, Marble Arch and Fingal's Cave demonstrate very different forms of cave development.

Show cave, cavern, mine or natural shelter?

The terms are often used loosely.

Cave

A natural underground void large enough for a person to enter.

Cavern

Usually a large cave or chamber, though attractions may use the word as part of a historic name.

Show cave

A natural cave adapted for public visits through paths, lighting, steps and guided or self-guided access.

Mine

An underground space excavated to remove minerals, stone or metal ore. Mines may intersect natural caves.

Sea cave

A cave created mainly through wave erosion along a coast.

Rock shelter

A shallow natural opening that may have archaeological importance without extending deeply underground.

Speedwell and Sygun contain substantial human-made workings, while Fingal's and Smoo are coastal caves. Understanding the difference improves the visit rather than reducing its appeal.

How caves form

Most British show caves occur in limestone.

Rainwater absorbs carbon dioxide from the air and soil, becoming mildly acidic. Over immense periods, this water enters cracks and slowly dissolves the limestone.

As passages enlarge, streams may move underground and create chambers. When mineral-rich water drips into open air within the cave, it can deposit calcite.

This produces formations such as:

• Stalactites: Hanging from the ceiling
• Stalagmites: Growing upward from the floor
• Columns: Formed when the two join
• Flowstone: Sheets of mineral deposited across walls or floors
• Curtains: Thin hanging sheets of calcite
• Straws: Delicate hollow stalactites
• Rimstone pools: Raised mineral edges around pools

These formations grow extremely slowly and should never be touched unless the attraction explicitly permits it.

Planning a cave visit

Before travelling, check:

• Whether booking is required
• Guided or self-guided format
• Tour duration
• Number of steps
• Low headroom
• Narrow passages
• Minimum age
• Footwear requirements
• Wheelchair access
• Photography rules
• Current water levels
• Seasonal opening
• Parking and public transport
• Whether children can manage darkness
• Whether bags are restricted
• The last tour time

Arrive early for guided visits. Cave tours cannot always admit late passengers once the group has entered.

What to wear underground

Caves remain cool even during summer.

Bring:

• A light warm layer
• Shoes with grip
• Clothing suitable for damp conditions
• A waterproof layer for exposed approaches
• Secure glasses
• A small bag rather than a large backpack
• Required medication

Avoid sandals, high heels and clothing that prevents bending or climbing steps.

Hard hats are provided where necessary. They protect against low rock rather than making unsafe movement acceptable.

Cave safety

Managed show caves are generally safe when visitors follow instructions.

Important rules include:

• Stay on the public route.
• Do not cross barriers.
• Follow the guide.
• Do not touch formations.
• Supervise children closely.
• Use handrails.
• Do not run.
• Do not enter flooded passages.
• Avoid flash where prohibited.
• Report illness or panic immediately.
• Do not leave the group on a guided tour.
• Never enter an unmanaged cave without suitable knowledge and equipment.
• Check tides before approaching sea caves.
• Treat wet limestone as slippery.
• Respect closures.

Wild caves can flood rapidly even when rain falls several miles away. Technical caving should be undertaken only with appropriate training, equipment and local knowledge.

Accessibility and sensory planning

Caves create unavoidable physical and sensory challenges.

Check for:

• Long staircases
• Low ceilings
• Narrow passages
• Darkness
• Coloured lighting
• Echoes
• Running water
• Confined boats
• Slippery surfaces
• Lack of toilets underground
• Limited emergency exits
• Restricted assistance-dog access
• No pushchairs
• Claustrophobia triggers
• Guided-tour pace

Some attractions provide virtual tours or surface exhibitions for visitors unable to enter. Marble Arch Caves has also developed virtual-access options, improving the experience for people who cannot complete the physical cave route.

Caves and conservation

Caves are fragile ecosystems and geological archives.

Responsible management may include:

• Monitoring visitor numbers
• Controlling lighting
• Preventing algae growth
• Protecting bats
• Maintaining water quality
• Restricting access to sensitive passages
• Supporting archaeological research
• Avoiding unnecessary touching
• Managing carbon dioxide levels
• Recording cave climate
• Working with caving organisations
• Closing routes during flooding
• Protecting surrounding catchments

The visible show-cave route is often only a small part of a much larger system. Restricted access protects formations, wildlife and unexplored passages.

Frequently asked questions

What is the best cave to visit in the UK?

Gough's Cave at Cheddar is the strongest all-round choice because it combines a substantial show cave, important archaeology and the wider Cheddar Gorge landscape.

What is the longest show cave in Britain?

White Scar Cave describes itself as Britain's longest show cave. Its public tour covers approximately one mile and lasts about 80 minutes.

What is the best cave in Wales?

Dan-yr-Ogof and the National Showcaves Centre provide the most extensive public cave attraction in Wales.

What is the best cave in Scotland?

Smoo Cave is the best accessible mainland cave. Fingal's Cave is the most spectacular sea cave but requires a boat journey and suitable conditions.

What is the best cave in Northern Ireland?

Marble Arch Caves is Northern Ireland's leading show cave and an important active river-cave system.

Are caves suitable for young children?

Many show caves welcome children, but darkness, steps, echoes and confined spaces may be difficult. Check minimum ages and route details.

Are caves cold inside?

Yes. Temperatures remain relatively stable and can feel cold compared with summer conditions outside.

Can wheelchairs enter show caves?

Access varies substantially. Natural gradients, narrow passages and steps make many caves inaccessible, although some provide adapted routes or virtual experiences.

Can visitors touch stalactites?

Usually not. Oils and dirt from hands can damage formations and interfere with future mineral deposition.

Do cave tours operate in heavy rain?

Some do, but active river caves may close or alter tours because of flooding. Marble Arch and Smoo are particularly affected by water conditions.

Final thoughts

Britain's caves reveal how water, rock and human history interact beneath the surface.

Gough's Cave and Kents Cavern connect geological spaces with evidence of ancient people. White Scar and Dan-yr-Ogof demonstrate the scale of Britain's limestone systems, while Marble Arch shows that cave formation is still visibly active through underground rivers.

Smoo and Fingal's Cave offer something different again. Their relationship with the sea, weather and remote landscape makes access less predictable, but also more memorable.

Choose according to the experience you want. For a complete family attraction, visit Dan-yr-Ogof or Wookey Hole. For a long and physical show-cave tour, choose White Scar. For archaeology, visit Kents Cavern. For a natural spectacle shaped by the Atlantic, travel north to Smoo or Staffa.

Whichever cave you enter, remember that the public route is only a carefully managed window into a much larger and more fragile underground world.
