Tyning's Barrow Swallet

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.

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

Goatchurch Cavern is a cave on the edge of Burrington Combe in the limestone of the Mendip Hills, in Somerset, England.

Reservoir Hole is a cave in Cheddar Gorge in Somerset, southwest England. It contains what is believed to be the largest chamber yet found under the Mendip Hills. The cave was first dug out in 1951 by members of Wessex Cave Club, and further progress was made in 1965 when "Moonmilk Chamber" was reached with the use of blasting. "Grand Gallery" was discovered in 1969, "Topless Aven" in 1970 and "Golgotha Rift" in 1973.In September 2012, after four years' work clearing a 100 metres (330 ft) long passage, a group of diggers broke into a new chamber which was found to be 30 metres (98 ft) high and 60 metres (200 ft) long. Prior to the discovery, the largest void under the Mendip Hills was thought to be "Main Chamber" in GB Cave, which is 23 metres (75 ft) high. Before the find in 2012, the cave was already noted for a number of fine formations, and the newly discovered chamber, which has been named “The Frozen Deep”, contains pure-white pillars 5 metres (16 ft) tall, as well as many stalagmites and stalactites.The possibility of a connection between Reservoir Hole and Gough's Cave, one of the show caves in Cheddar Gorge, has been raised, as the two caves are in close proximity. The stream in Reservoir Hole emerges only a short distance down Cheddar Gorge.

Sidcot Swallet is a cave near Burrington Combe, in the Carboniferous Limestone of the Mendip Hills, in Somerset, England. It was named after the Sidcot School Speleological Society who explored it in 1925.A swallet, also known as a sinkhole, sink, shakehole, swallow hole or doline, is a natural depression or hole in the surface topography caused by the removal of soil or bedrock, often both, by water flowing beneath. After Goatchurch Cavern, Sidcot Swallet is probably the most popular cave on Mendip for novice parties. What it lacks in length or depth is adequately compensated for by its sporty squeezes and narrow crawls. Despite its popularity, many calcite formations still remain intact in the farthest reaches of the cave.

Read's Cavern is a cave at Burrington Combe, Somerset, England, in which traces of Iron Age occupation have been found. It lies under Dolbury Hill. Its large main chamber has a boulder ruckle floor and is parallel to a cliff face. The cave was excavated by the University of Bristol Spelæological Society (UBSS) in the 1920s, when relics of Iron Age occupation were found.The UBSS excavation followed the removal of 21 tonnes of limestone material below a cliff where a stream sinks. Among the finds were ironwork described as slave shackles.After its discovery, the cave was first known as Keltic or Celtic Cavern until the Ordnance Survey decided that it should be known as Read's Cavern, after Mr. R. F. Read, the discoverer. It has also been called "Gough's Cave".

Black Down is the highest hill in the Mendip Hills, Somerset, in south-western England. Black Down lies just a few miles eastward of the Bristol Channel at Weston-super-Mare, and provides a view over the Chew Valley. The summit is marked with an Ordnance Survey trig point, the base of which has been rebuilt by the Mendip Hills AONB authority. The shortest route of ascent goes from the Burrington Combe car park and is approximately 1 km long. Black Down is an open-access area mostly consisting of moors, with dense cover of associated vegetation such as heather and bracken. According to a local organization's newsletter, the name "Black Down" comes from the Saxon word 'Blac' or 'Bloec' meaning bleak, 'Dun' meaning down or fort.

Burrington Combe is a Carboniferous Limestone gorge near the village of Burrington, on the north side of the Mendip Hills Area of Outstanding Natural Beauty, in North Somerset, England. "Combe" or "coombe" is a word of Celtic origin found in several forms on all of the British Isles, denoting a steep-sided valley or hollow. Burrington Combe is a gorge through the limestone hills although there is now no river running through it. Various cave entrances are exposed which have been occupied by humans for over 10,000 years, with a hillfort being built beside the combe in the Iron Age. The geology has led to a diversity of plant life. According to legend Augustus Montague Toplady was inspired to write the hymn Rock of Ages while sheltering under a rock in the combe, although recent scholars have disputed this claim.

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.

Aveline's Hole is a cave at Burrington Combe in the limestone of the Mendip Hills, in Somerset, England. The earliest scientifically dated cemetery in Britain, 10,200 and 10,400 years old, was found at Aveline's Hole, constituting the largest assemblage of Mesolithic human remains found in Britain. Much of the collection has been lost due to pillaging, poorly recorded investigation and war, and although more than fifty individuals are represented, there are only two complete skeletons. Perforated animal teeth, red ochre and seven pieces of fossil ammonite, suggest that some of the bodies were adorned.A series of inscribed crosses found on the wall of the Aveline's Hole cave are believed to date from the early Mesolithic period just after the Ice Age. The pattern is said to be comparable with others known from Northern France, Germany and Denmark. A gate has been installed in the cave to protect the engraving, after consultations between English Heritage and other interested parties, including the landowner and English Nature. The cave was rediscovered in 1797 by two men digging for a rabbit. The cave was excavated and the entrance enlarged in 1860 by William Boyd Dawkins who named it after his mentor William Talbot Aveline.Access to the cave is controlled by the University of Bristol Spelæological Society and is restricted during the bat hibernation season.

Batts Combe quarry, grid reference ST460550 is a limestone quarry on the edge of Cheddar village on the Mendip Hills, Somerset, England. It has been operating since the early 20th century and is currently owned and operated by Singleton Birch Ltd. The output in 2005 was around 4,000 tonnes of limestone per day, one third of which was supplied to an on-site lime kiln, the remainder being sold as coated or dusted aggregates. The limestone at this site is close to 99% carbonate of calcium and magnesium (dolomite). In former years it was a major supplier of limestone for railway track ballast purposes. A lime-burning kiln at the site was closed for a while in 2006 after testing showed quicklime dust was escaping into the atmosphere. The kiln, which produced 200,000 tonnes of quicklime a year for use in the steel industry, required £300,000 of investment to resolve the problems. The closure followed an earlier warning from the Environment Agency when the company was notified that it should tighten up procedures at the site. Quicklime dust is a health hazard, which in large quantities can cause skin irritation and damage to the eyes and throat. In March 2009 however the lime kiln closed, supposedly indefinitely, following a drop in demand from the site's sole customer, Corus.; the quarry has since been taken over by Melton Ross, Lincolnshire-based Singleton Birch. There is some evidence of a Bronze Age field system at the site. Boxes were placed in Hanson woodland adjoining the company's Batts Combe quarry to encourage dormice to breed, and monitored with the help of pupils from Wells Cathedral School.
