Gough's Cave ( GOF) is located in Cheddar Gorge on the Mendip Hills, in Cheddar, Somerset, England. The cave is 115 m (377 ft) deep and is 3.405 km (2.12 mi) long, and contains a variety of large chambers and rock formations. It contains the Cheddar Yeo, the largest underground river system in Britain.

Cheddar Gorge is a limestone gorge in the Mendip Hills, near the village of Cheddar, Somerset, England. The gorge is the site of the Cheddar show caves, where Britain's oldest complete human skeleton, Cheddar Man, estimated to be 9,000 years old, was found in 1903. Older remains from the Upper Late Palaeolithic era (12,000–13,000 years ago) have been found. The caves, produced by the activity of an underground river, contain stalactites and stalagmites. The gorge is part of a Site of Special Scientific Interest called Cheddar Complex.Cheddar Gorge, including the caves and other attractions, has become a tourist destination. In a 2005 poll of Radio Times readers, following its appearance on the television programme Seven Natural Wonders (2005), Cheddar Gorge was named as the second greatest natural wonder in Britain, surpassed only by Dan yr Ogof caves. The gorge attracts about 500,000 visitors per year.

The Perch (grid reference ST480532) is a 72.1 hectare (178.2 acre) biological Site of Special Scientific Interest close to Cheddar Gorge in the Mendip Hills, Somerset, England. It received SSSI notification in 1990. This site is important because it supports populations of nationally rare and scarce plants, together with grassland and woodland habitats which are nationally restricted in distribution.The site is located on the south side of the Mendip Hills occupying a position on a steep-sided ridge which runs north to south. The underlying rocks are almost entirely carboniferous limestone with a small amount of Triassic dolomitic conglomerate.The nationally rare purple gromwell (Lithospermum purpurocaeruleum) and the nationally scarce Ivy Broomrape (Orobanche hederae) also occur. Three species of orchid occur in these grassland areas: the Green-winged Orchid (Orchis morio), the pyramidal orchid (Anacamptis pyramidalis) and the Autumn Ladies'-tresses (Spiranthes spiralis). Two nationally rare plants, the Cheddar pink (Dianthus gratianopolitanus) and the Cheddar bedstraw (Galium fleurotii) are found on this site, as are two nationally scarce species: the rock stonecrop (Sedum forsterianum) and the spring cinquefoil (Potentilla tabernaemontani).This variety of habitats ensures that a wide range of fauna occurs on the site. In total 22 species of mammal have been recorded including a strong population of dormouse (Muscardinus avellanarius) and five species of bat, including the Greater Horseshoe bat (Rhinolophus ferrumequinum) and Lesser Horseshoe bat (Rhinolophus hipposideros) which use the site for feeding. One small roost of lesser horseshoe bats is known. Both species of horseshoe bat are nationally rare. Thirty species of birds are known to breed within this site and at least 23 species of butterfly breed here.

Kingdown and Middledown (grid reference ST480532) is a 5.7 hectare (14.1 acre) biological Site of Special Scientific Interest near Cheddar in the Mendip Hills, Somerset, notified in 1991. This site, which is in two parts, is situated on the plateau of the Mendip Hills and supports populations of two nationally rare plant species. Kingdown is at the end of a dry valley where Carboniferous Limestone outcrops as a small cliff, opposite which is a small disused limestone quarry. Covering some of the rock outcrops are clumps of Cheddar Pink (Dianthus gratianopolitanus), which is a nationally rare species. The nationally scarce species Soft-leaved Sedge (Carex montana) and Cheddar Bedstraw (Galium fleurotii) are also found here.

Cox's Cave is in Cheddar Gorge on the Mendip Hills, in Somerset, England. It is open to the public as a show cave. The cave is named after mill owner George Cox who discovered it in 1837, while quarrying limestone for a new building. Cox immediately opened it as a show cave the following year and ran it as a private enterprise until the landowner, Thomas Thynne, 5th Marquess of Bath, took it over at the beginning of the 20th century. It was connected by a tunnel to the adjacent artificial Pavey's Cave in 1987.The cave consists of seven small grottoes, joined by low archways. One section of the cave is known as the Home of the Rainbow, where traces of minerals have been brought in from the surface, and have given the stalagmites a wide range of colour, from nearly black, green, and orange to pure white. The famous French speleologist Édouard-Alfred Martel visited this cave and declared that "out of 600 caves, Cox's was admired the most".

The Cheddar Complex is a 441.3-hectare (1,090-acre) biological Site of Special Scientific Interest near Cheddar around the Cheddar Gorge and north east to Charterhouse in the Mendip Hills, Somerset, England, notified in 1952. The very large area includes 4 SSSIs formerly known as: Cheddar Gorge SSSI; August Hole/Longwood Swallet SSSI; GB Cavern Charterhouse SSSI; and Charterhouse on-Mendip SSSI. It is part owned by the National Trust, commercial landowners including the Marquess of Bath's Longleat Estate; and part managed by the Somerset Wildlife Trust.

GB Cave is a cave between Charterhouse and Shipham in the limestone of the Mendip Hills, in Somerset, England.The cave was first entered on 19 November 1939, after ten months of digging, by the University of Bristol Spelæological Society, and was named in recognition of the two members, F. J. Goddard and C. C. Barker, who had done most of the work involved in its discovery. The cave is located within the Cheddar Complex and the 17-acre GB Gruffy nature reserve and is close to Charterhouse Cave, the deepest cave in the region.Ladder Dig broke through in 1966 to gain access to the extremely well-decorated Bat Passage.The entrance to the cave is kept locked, and access is controlled by the Charterhouse Caving Company.

Charterhouse Cave, on the Mendip Hills in Somerset, is the deepest cave in southern England.

Rhino Rift is a cave near Charterhouse, in the Carboniferous Limestone of the Mendip Hills, in Somerset, England. The cave is part of the Cheddar Complex SSSI. It is 253 m in length and reaches a depth of 147 m.The cave was discovered in 1971 after a successful dig by members of the Wessex Cave Club. Previous digging by the University of Bristol Spelaeological Society had unearthed remains of extinct animals, hence the cave's name.The cave is locked and access is controlled by the Charterhouse Caving Company.

Tyning's Barrow Swallet (grid reference ST47135638) is a cave between Charterhouse and Shipham in the limestone of the Mendip Hills, in Somerset, England. The cave is close to GB Cave and also to Charterhouse Cave, the deepest cave in the region. Tyning's Barrow Swallet is 1.29 km (4,200 ft) in length and reaches a depth of 132 m (433 ft).

Mendips Raceway is a motorsport venue in the Mendip Hills in Somerset, England. It is located on the rim of Batts Combe quarry between Shipham and Charterhouse. The oval shaped circuit is used for racing hot rods, stock cars, Hotstox, bangers and demolition events. The circuit, which was opened in 1969, features an oval and a figure of eight layout. The latter is used for different classes of banger racing which sometimes involve towing caravans, or feature specialist vehicles such as hearses or Reliant Robins. Until 2018, it hosted the West of England Championship for Rods every August. It has also hosted the BriSCA F2 World Championship Final several times

The Longwood Swallet is a cave near Charterhouse, in the Carboniferous Limestone of the Mendip Hills, in Somerset, England. The cave is part of the Cheddar Complex SSSI and is connected to August Hole. It is 1.65 km in length and reaches a depth of 175m.The cave was discovered in September 1944 by boys from Sidcot School.The picture shown is not the Longwood Swallet, it is Longwood Valley Sink. Longwood Swallet's entrance is a lidded concrete block construction. A (non-free) picture of Longwood Swallet entrance is available here The cave is locked and access is controlled by the Charterhouse Caving Company. There is a warning sign posted at the entrance to the cave about flooding. This has always been a problem, but is more pronounced due to the extraction of water from the spring at Charterhouse. When the pumps owned by Bristol Water stop this can cause a flood wave to travel down the stream and into the cave.
