It was one of Australia most heavily glaciated areas, and includes Mt Ossa (1, 617m) - Tasmania's highest peak - and LakeStClair, Australia's deepest natural freshwater lake (167m).
There are fabulous day walks at both Cradle Valley in the north and Cynthia Bay (Lake StClair) in the south, but it is the outstanding 80.5km Overland Track between the two that has turned this park into a bushwalkers' Mecca.
