Enjoy the stunning cave formations, rich colours and sparkling crystals. Gunns Plains Cave is in the Gunns Plains State Reserve, approximately 30 kilometres south of Ulverstone in northwest Tasmania. This ten hectare area was one of the earliest cave reserves in Tasmania, being proclaimed a State Reserve in 1918.

The cave was discovered in 1906 by Bill Woodhouse during a hunting trip after, it is reputed, his dogs fell into a hole that formed part of the cave.
