Lake St. Clair is at the southern end of Cradle Mountain – Lake St. Clair National Park. The car park and visitors centre are at Cynthia Bay. This is also the end point for people completing the Overland Track from north to south. From here there are a number of good day walks as well as longer walks. We decided to head out there for a long weekend, with a good weather forecast, to do a bit of exploring, including a walk and camping at Shadow Lake and to do the Mt Rufus Circuit.
