West Coast Track
This is without doubt the greatest wilderness walk in Tasmania. This is because the route takes about one month to walk 165 km of coastline the route is logical and difficult to escape from, there are no tracks or signs of people and the coastline keeps varying. It is not a trivial walk and takes considerable planning and walking experience to be successful. There aren't many in the world where you can follow a coastline for a month and be nowhere near anybody or any civilisation for the entire walk.
Tasmania's temperate wilderness is one of the few such left in the world. The West Coast is a pure wilderness walk no signs of other people or developments like tracks, campsites etc. For visitors from other countries, this will seem very rare and it is.
The route basically follows the west coast from Bathurst Harbour (Port Davey area) to Macquarie Harbour (Strahan). This is the southern half of the west coast of the state. This is wilderness walking par excellence. There are no ranger stations, no habitation and no marked walking tracks. The only signs of civilisation are the flotsam and jetsam washed up on the shore, some shipwrecks, a small lighthouse half way and some old overgrown vehicle tracks to the light (they now service the light by boat).
