Cradle Mountain-Lake St Clair National Park is located in the Central Highlands area of Tasmania (Australia), 165 km northwest of Hobart. The park contains many walking trails, and is where hikes along the well-known Overland Track usually begins. Major features are Cradle Mountain and Barn Bluff in the northern end, Mount Pelion East, Mount Pelion West, Mount Oakleigh and Mount Ossa in the middle and Lake St Clair in the southern end of the park. The park is part of the Tasmanian Wilderness World Heritage Area.
Access from the south (Lake St. Clair) is usually from Derwent Bridge on the Lyell Highway. Northern access (Cradle Valley) is usually via Sheffield, Wilmot or Mole Creek. A less frequently used entrance is via the Arm River Track, from the east.
