The Overland Track is a 65km alpine walk through the Cradle Mountain-Lake St Clair National Park within the Tasmanian Wilderness World Heritage Area. It winds from Cradle Mountain to Lake St Clair over alpine plains, past glacial mountains, rivers and lakes and through temperate rainforests. The track may originally have been used as an Aboriginal access track. The Aboriginals were persecuted by the European settlers who arrived in the 1800's. In the 1910's Gustav and Kate Weindorfer began campaigning for the area to become a national park. They built the Waldheim Chalet in 1912, to provide rugged accommodation for nature lovers. There are a number of historic huts along the track, each with their own story. We did a guided 6 day private hut to hut walk with Taswalks. We climbed Mount Ossa, Tasmania's highest mountain at 1617 metres, swam in lakes and rivers and ended with a boat ride on Lake St Clair.
