Mount Anne is the nineteenth highest mountain in Tasmania, but the highest in south-west Tasmania, adding to its appearance of prominence. It dominates the area surrounding Lake Pedder.
Although a primarily dolerite structure, it has a large sub-structure of dolomite, which contains an extensive cave system. This system includes the famous 'Anna-a-Kananda' cave - one of the deepest caves in Australia. Several cavers have been killed trying to explore its depths.
Mount Anne has a superb region of ancient Gondwanan type vegetation on its north-east ridge, some of which are amongst the oldest surviving plant species on the planet.
