Cradle Mountain-Lake St Clair National Park
Park Tasmanian national park with alpine lakes and peaks
Tasmania’s Cradle Mountain-Lake St Clair National Park contains alpine peaks, glacial lakes and the multi‑day Overland Track. Walkers, wildlife watchers and photographers arrive for tarns, button‑grass plains and frequent wombat sightings.
Cradle Mountain-Lake St Clair National Park is a protected area in central Tasmania, known for its high mountain scenery, glacial lakes and extensive walking trails. The park forms part of the Tasmanian Wilderness World Heritage Area and contains both alpine and cool temperate rainforest environments.
The park’s best-known features are Cradle Mountain, rising to about 1,545 metres and overlooking Dove Lake, and Lake St Clair, which is the deepest freshwater lake in Australia with a maximum depth around 168 metres. The landscapes include glacially scoured peaks, moraine and deep lakes.
A key attraction is the Overland Track, a marked 65-kilometre route that links Cradle Mountain in the north to Lake St Clair in the south and is typically walked over 5-7 days. Visitor hubs and ranger services are provided at the main trailheads and near the lakes to manage access and preserve the area.
The park was established in the early 20th century and has been managed to conserve its unique glacial and ecological features while supporting bushwalking and nature-based tourism.

Tips for Visiting Cradle Mountain-Lake St Clair National Park #
- Walk sections of the Overland Track as day-hikes if the full 65 km trek isn't on the itinerary - the Dove Lake circuit is a short, dramatic option.
- Arrive at dawn for mirrored reflections of Cradle Mountain on Dove Lake; late afternoon brings clouds and fewer people.
- If driving, use the Ronny Creek or Dove Lake car parks - Ronny Creek fills fast in summer, so aim for early arrival or use park shuttles.
- Most huts and lodges require advance booking months ahead during peak season (Dec-Feb).
