Giant's Hole is a well-known cave near Castleton in Derbyshire, consisting mostly of large passages.

[1] There is a complex system connecting the cave to Oxlow Cavern and Maskhill Mine to the south.

There are several major tributary passages and a high-level fossil series that provides an alternative route through the cave and makes up part of the classic "round trip".

East Canal has been dived to a depth of 24 metres (79 ft) in drought (but water levels are normally much higher).

[3] Since 2002, the Derbyshire Cave Rescue Organisation has attended 11 callouts to Giant's Hole, one of which resulted in a fatality.
