Mount Anne is the highest mountain in Tasmania’s Southwest (1423 meters). It is 11 km one way walk to the base of the peak and exposed climbing to the very top. To enjoy the views of Lake Pedder and the surrounding area, going up to Eliza Plateau would be enough and twice shorter.
Mount Anne Circuit is a multi day walk that can be completed in a few days. It is slightly technical and exposed at Lighting Ridge, but that what makes it very fun if you are looking for some challenge.
