More than 8000 walkers each year complete the track. Officially, the track runs for 65 km from Cradle Mountain to Lake St Clair. However, many choose to add the hike along Lake St Clair as a natural extension, bringing the length to 82 km. The track winds through terrain ranging from sheer mountains, temperate rainforest, wild rivers and alpine plains all in the Tasmanian Wilderness World Heritage Area.

Aside from the main track there are also several alternative side tracks, including to the summits of Cradle Mountain and Mount Ossa, the tallest mountain in Tasmania (1617 m). Also within reach are a group of tarns called The Labyrinth and Lake St Clair (the deepest lake in Australia). World-renowned for its pristine environment and beauty, the walk has been compared to New Zealand's Milford Track.

Walkers complete the trail in 5–6 days. This is normally done from north to south, which is the mandatory direction between 1 October and 31 May. The record time is 7 hours and 25 minutes, achieved by Andy Kromar during the Cradle Mountain Run.
