Tasmania: South Coast Track walk.
This walk has got it all: beach, mountain, mud, waterfalls, bush, wildly varying weather and very few people. The south coast track in Tasmania, a remote wilderness walk that was created as a route for stranded boaties to escape back to safety. Only about 100 people a year walk on this track, so it is a privileged, private experience. I nearly had to cancel due to a gall stone attack. The marvels of modern medicine enabled me to walk just under 3 weeks after the operation.
