We did the Bay of Fires Walk in Tasmania earlier in 2011, and it was a wonderful experience. Just you and 12 other people on an isolated beach, alone (or relatively in today's world) with nature.
Recently I stumbled across another great walk of Tasmania, the Maria Island Walk. We looked at doing this walk at Easter 2012, but it's so popular that it was already booked out!
On their slogan is "four days that will last a lifetime". The walk covers 34 km, on a small Island off Tasmania. There are different accommodation types for each night, with extraordinary food along the way.
So who's coming with me?
