The Greater Patagonia Trail (GPT) is a 3,000km route running north-south through Chilean and Argentinian Patagonia.
I call it a “route” rather than a “trail” because, the GPT is more of an idea of a trail, rather than an actual trail at this point. Much different from the Pacific Crest Trail or the Appalachian trail, the route does not have one clear trail to follow. The route follows horse trails, foot paths, dirt roads, and rivers from Santiago, Chile all the way to a glacier just south of Fitz Roy, Argentina. Sometimes the “trail” map simply shows a straight line moving in a certain direction, and hikers are expected to use GPS or map and compass to figure out how to bush-crash their way there.
