Tasmanian short walks
Tasmania has some of the most spectacular walks in the country. The Overland Track is probably the most famous but Tassie has plenty of scope for less (and more) arduous hikes. As an added bonus, it's a fairly small state, and there are tour companies who run shuttle buses to and from some of the more popular trailheads.
Looking north over Lake Gordon from the summit of Mt Wedge. The Mt Wedge track is a a reasonably steep day walk up and back from the carpark off Gordon River Road, a few hours drive from Hobart.
Schouten Island is just off the end of the Freycinet Peninsula on the east coast of Tasmania. There wasn't much walking involved in this trip - we paid a bloke in Coles Bay to ferry us there and back by boat. I think the island is separated from the peninsula by about a kilometre or so of water. An excellent place for snorkeling and some pleasant day walking. This beach is just near the main campsite.
