The Overland Track is one of Australia's most famous bush treks, situated in the Cradle Mountain-Lake St Clair National Park, Tasmania. 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.
