Last updated

This is an incomplete list of caves in the United Kingdom , including information on the largest and deepest caves in the UK.

Contents

Longest, deepest and largest

The longest cave system in the UK is the Three Counties System in the Yorkshire Dales, with 86.7 km (53.9 mi) of passageways. It includes the Ease Gill system, the Notts Pot / Ireby Fell Cavern system, the Lost John's Cave system, and the Pippikin Pot system, all of which are connected. [1]

A sea cave on the north side of Calder's Geo in Shetland was measured in 2014 at over 20 metres (66 ft) high and with a floor area of around 5,600 square metres (60,000 sq ft). This makes it the largest known cave chamber in the United Kingdom. [3] [4]

A chamber in Reservoir Hole, Cheddar Gorge called “The Frozen Deep” was discovered in 2012 and found to be 30 metres (98 ft) high and 60 metres (200 ft) long. [5]

Gaping Gill

Gaping Gill is a natural cave in North Yorkshire, England. It is one of the unmistakable landmarks on the southern slopes of Ingleborough – a 98-metre (322 ft) deep pothole with the stream Fell Beck flowing into it. After falling through one of the largest known underground chambers in Britain, the water disappears into the bouldery floor and eventually resurges adjacent to Ingleborough Cave.

Ogof Craig a Ffynnon

Ogof Craig a Ffynnon is a cave in Wales. The cave is about 7 km in length and is located at the base of a quarried rockface in the Clydach Gorge. Water flowing out of the cave is a resurgence of water draining off Llangatock Mountain above.

Cave Diving Group UK based cave diver training and certification agency

The Cave Diving Group (CDG) is a United Kingdom-based diver training organisation specialising in cave diving.

Ogof Ffynnon Ddu Cave in South Wales, United Kingdom

Ogof Ffynnon Ddu, also known informally as OFD, is a cave under a hillside in the area surrounding Penwyllt in the Upper Swansea Valley in South Wales. It is the second longest cave in Wales and the deepest in the United Kingdom.

Marble Arch Caves series of natural limestone caves in County Fermanagh, Northern Ireland

The Marble Arch Caves are a series of natural limestone caves located near the village of Florencecourt in County Fermanagh, Northern Ireland. The caves are named after the nearby Marble Arch, a natural limestone arch at the upstream end of Cladagh Glen under which the Cladagh River flows. The caves are formed from three rivers draining off the northern slopes of Cuilcagh mountain, which combine underground to form the Cladagh. On the surface, the river emerges from the largest karst resurgence in Ireland, and one of the largest in the United Kingdom. At 11.5 kilometres (7.1 mi) the Marble Arch Caves form the longest known cave system in Northern Ireland, and the karst is considered to be among the finest in the British Isles.

Pit cave Cave with significant vertical passages

A pit cave, shaft cave or vertical cave—or often simply called a pit or pot ; jama in South Slavic languages scientific and colloquial vocabulary —is a type of cave which contains one or more significant vertical shafts rather than being predominantly a conventional horizontal cave passage. Pit caves typically form in limestone as a result of long-term erosion by water. They can be open to the surface or found deep within horizontal caves. Among cavers, a pit is a vertical drop of any depth that cannot be negotiated safely without the use of ropes or ladders.

St Cuthberts Swallet Cave in the Mendip Hills, Somerset, England

St Cuthbert's Swallet is the second longest, and most complex, cave on the Mendip Hills, in Somerset, England. It forms a major part of the Priddy Caves system and water entering this swallet re-emerges at Wookey Hole. St Cuthbert's Swallet is part of, and lies underneath, the Priddy Pools Site of Special Scientific Interest.

Great Douk Cave

Great Douk Cave is a shallow cave system lying beneath the limestone bench of Ingleborough in Chapel-le-Dale, North Yorkshire, England. It is popular with beginners and escorted groups, as it offers straightforward caving, and it is possible to follow the cave from where a stream emerges at a small waterfall to a second entrance close to where it sinks 600 yards (549 m) further up the hill. It lies within the Ingleborough Site of Special Scientific Interest.

Rumbling Hole

Rumbling Hole is a cave on Leck Fell, in Lancashire, England. Its entrance is a 50-metre (160 ft) deep fenced shaft, and it rapidly descends a series of pitches to a low aqueous passage that has been connected to Lost Johns' Cave. It is part of the Three Counties System, an 87-kilometre (54 mi) cave system that spans the borders of Cumbria, Lancashire, and North Yorkshire.

Lost Johns Cave Cave in the United Kingdom

Lost Johns' Cave is an extensive cave system on Leck Fell, Lancashire, England. With its three major vertical routes it is a popular place to practise single-rope technique (SRT) because of the opportunity for exchange trips. Also it can be safely visited on wet days because many of the pitches can be rigged out of the water. It is an important part of the Three Counties System.

Leck Fell

Leck Fell is a Site of Special Scientific Interest in Lancashire, England. An area of typically heavily grazed open moorland of rough grass and remnant patches of heather with little or no tree cover, it is characterised by the virtual absence of surface drainage and an extensive subterranean drainage network resulting in cave systems and numerous sinkholes. It surrounds the high point of Gragareth 627 metres (2,057 ft) between Leck Beck and Kingsdale.

Langcliffe Pot

Langcliffe Pot is a cave system on the slopes of Great Whernside in Upper Wharfedale, about 3 kilometres (1.9 mi) SSE of Kettlewell in North Yorkshire. It is part of the Black Keld Site of Special Scientific Interest where the "underground drainage system which feeds the stream resurgence at Black Keld is one of the largest and deepest in Britain, although only a small proportion of its cave passages are accessible at present." Mossdale Caverns is also part of the Black Keld SSSI. Although a considerable length of passage has been explored in Langcliffe Pot, the current end is over 170 metres (560 ft) above the resurgence, and over 4 kilometres (2.5 mi) in distance. A trip to the far end has been described as "one of the most serious undertakings in British Caving".

Carreg Cadno

Carreg Cadno is a hill five miles northeast of Abercraf in the county of Powys, south Wales. It lies within the Brecon Beacons National Park and Fforest Fawr Geopark. Its summit at OS grid ref SN 874161 reaches a height of 538m / 1763 ft above sea level. The hill is within the Ogof Ffynnon Ddu National Nature Reserve which is owned and managed by the Countryside Council for Wales.

Short Drop Cave - Gavel Pot System

Short Drop Cave and Gavel Pot are different entrances into the same cave system on Leck Fell, in Lancashire, England. The main top entrance, Short Drop Cave, is a small hole in a fenced off shakehole near the main stream sink; Gavel Pot, a window into the system, is a large fenced shakehole some 40-metre (130 ft) deep requiring tackle to descend. There are two other smaller entrances into Short Drop Cave. At its base the system links via a sump with Lost Johns' Cave, and is part of the Three Counties System, an 87 kilometres (54 mi) cave system which spans the borders of Cumbria, Lancashire, and North Yorkshire.

Disappointment Pot

Disappointment Pot is one of the entrances to the Gaping Gill cave system, located in a steep grassy shakehole some 120 metres (130 yd) south-east of Gaping Gill Main Shaft. Its mainly narrow stream passage descends a number of small shafts to enter the main system as a major inlet of Hensler's Master Cave. It lies within the designated Ingleborough Site of Special Scientific Interest.

Flood Entrance Pot

Flood Entrance Pot is one of the entrances to the Gaping Gill cave system located about 300 metres (330 yd) south of Gaping Gill Main Shaft. It was the first alternative entrance into the main system to be explored, and it is now a popular entrance into the system, with a fine 38-metre (125 ft) pitch landing in Gaping Gill's South-East Passage. It lies within the designated Ingleborough Site of Special Scientific Interest.

Yordas Cave

Yordas Cave is a solutional cave in Kingsdale, North Yorkshire, England. It has been renowned since the eighteenth century as a natural curiosity, and was a show cave during the nineteenth century. It is now a popular destination for cavers, walkers, and outdoor activity groups.

Deaths Head Hole

Death's Head Hole is a cave on Leck Fell, in Lancashire, England. Its entrance is a 64-metre (210 ft) deep shaft. It leads into Lost Johns' Cave, and is part of the Three Counties System, an 87-kilometre (54 mi) cave system which spans the borders of Cumbria, Lancashire, and North Yorkshire.

Three Counties System

The Three Counties System is a set of inter-connected limestone solutional cave systems spanning the borders of Cumbria, Lancashire and North Yorkshire in the north of England. The possibility of connecting a number of discrete cave systems in the area to create a single super-system that spans the county borders was first proposed by Dave Brook in 1968, and it was achieved in 2011. The system is currently over 86 kilometres (53 mi) long, making it the longest in the UK and the twenty-ninth longest in the world, and there continues to be scope for considerably extending the system.
