Odin Mine

Odin Mine is a disused lead mine in the Peak District National Park, situated at grid reference SK133835. It lies on a site of 25 hectares near the village of Castleton, England. It is the oldest documented mine in Derbyshire and is thought to be one of the oldest lead mines in England. The mine is a Scheduled Ancient Monument and has biological and geological significance within the Castleton Site of Special Scientific Interest.

Treak Cliff Cavern

Treak Cliff Cavern is a show cave near Castleton in Derbyshire, England. It is part of the Castleton Site of Special Scientific Interest and one of only two sites where the ornamental mineral Blue John is still excavated (the other is the nearby Blue John Cavern). As part of an agreement with English Nature, the Blue John that can be seen in the show cave is not mined but it is extracted in small quantities from other areas of the cave and made into saleable items like bowls, jewellery, and ornaments. The cave comprises three sections, the Old Series, discovered by lead miners in the 18th century, the New Series, discovered during blasting in the 1920s, and the New Series Extensions, discovered in 2014. Only the Old Series contains Blue John, but the New Series is well decorated with flowstone, stalagmites, and stalactites. The New Series Extensions are also highly decorated, but are only accessible by experienced cavers. Three human skeletons and flint implements from the Neolithic era were found in a small cave nearby in 1921.

Mam Tor

Mam Tor is a 517 m (1,696 ft) hill near Castleton in the High Peak of Derbyshire, England. Its name means "mother hill", so called because frequent landslips on its eastern face have resulted in a multitude of "mini-hills" beneath it. These landslips, which are caused by unstable lower layers of shale, also give the hill its alternative name of Shivering Mountain. In 1979, the continual battle to maintain the A625 road (Sheffield to Chapel en le Frith) on the crumbling eastern side of the hill was lost when the road officially closed as a through-route, with the Fox House to Castleton section of the road being re-designated as the A6187. The hill is crowned by a late Bronze Age and early Iron Age univallate hill fort, and two Bronze Age bowl barrows. At the base of the Tor and nearby are four show caves: Blue John Cavern, Speedwell Cavern, Peak Cavern and Treak Cliff Cavern where lead, Blue John, fluorspar and other minerals were once mined. Mam Tor was declared to be one of the Seven Wonders of the Peak by Thomas Hobbes in his 1636 book De Mirabilibus Pecci.

Winnats Pass

Winnats Pass (or Winnats, as shown on some Ordnance Survey maps) is a hill pass and limestone gorge in the Peak District of Derbyshire, England. The name is a corruption of 'wind gates' due to the swirling winds through the pass. It lies west of the village of Castleton, in the National Trust's High Peak Estate and the High Peak borough of Derbyshire. The road winds through a cleft, surrounded by high limestone ridges. At the foot of the pass is the entrance to Speedwell Cavern, a karst cave accessed through a flooded lead mine, and which is a popular tourist attraction. In the 1930s, Winnats Pass was the location used for annual access rallies in support of greater access to the moorlands or the Peak District, around the time of the Mass Trespass of Kinder Scout. At their peak these were attended by up to 10,000 people. The permanent closure of the main A625 road at Mam Tor in 1979 due to subsidence has resulted in Winnats Pass being heavily used by road traffic. However, the narrowness of the road and its maximum gradient of over 28% has caused it to be closed to buses, coaches and vehicles over 7.5 tonnes (7.4 long tons; 8.3 short tons) in weight. The road regularly features in the Tour of the Peak cycle race each autumn.
