Speedwell Cavern
A boat trip through an 18th-century man-made underground lead mine canal, ending at a great natural cavern and a deep pool known as the 'Bottomless Pit'.
Speedwell Cavern began as an 18th-century lead mine. To transport ore, miners cut an underground waterway through the hillside. Visitors descend 105 steps, then take a small boat along a narrow tunnel for about 800 metres, finally reaching a natural cavern and a deep pool known as the 'Bottomless Pit'. The boat journey is unusual and suits families. The whole visit takes about an hour. The cave stays around 9°C, so bring a jacket. Admission costs about £20, and booking ahead is advised on weekends and holidays. It sits at the foot of Winnats Pass, about a 15-minute walk from Castleton.
