The Greater Patagonian Trail is the first long-distance trail in Chile/Argentina, proposed and established by Jan Dudeck (end 2013). There are hiking and horse trails that traverse remote valleys and mountain passes, created and maintained by local herdsmen and settlers. This long-distance trail joins up these paths and trails, and about 1500km has already been established (walked). One of the reasons why it’s called Greater Patagonian Trail is because most of it is actually outside the traditionally-defined Patagonia boundaries, in Southern Chile.
