Michael Deckebach summarized this conclusion after his 5-months adventure on the GPT with the following words: "The Greater Patagonian Trail is awesome, but (...) not designed for “purists” who get satisfaction from completing every inch of trail or touching every white blaze. Can it be done? Probably, but why try and fit a square peg into a round hole?”.
===Future Extensions of the GPT===
====Northbound====
Santiago de Chile is a suitable northern start (or finish) point and I’m not contemplating a further northern extension. The last metro/subway station Puente Alto provides an easy access and minimizes walking through an overcrowded mega-city. Santiago de Chile as the northern terminus is the point that provides the best possible contrast to the southern terminus of the GPT. It’s from metropolis to the back of beyond; it’s from semi-desert to ice fields.
I leave it to others to create a new trail that may start in Santiago and explores the Andes northbound. The Precordillera in the vicinity of Santiago offers some very attractive trails. There are even passes to cross the Andes from Chile into Argentina but creating a longer northbound trail that starts at Santiago or on a similar latitude in Argentina seems a bigger challenge than creating the GPT; at least if based on the same principles that I applied to the GPT: feasible and attractive for hiking and minimal road walking on routes with transit traffic. North of Santiago the Andes are very high and you either need to climb into really thin air and rocky terrain or you evade to the east or the west into the deserts on either side of the Andes. In my research I could simply not find similar suitable trails and the existing gravel roads are no option for me. North of Santiago water deficiency becomes an enormous challenge. Therefore most hikers that set themselves the goal to cross Chile or Argentina took primarily roads and this is what cautions me. But the challenge is out. You may go for it!
====Southbound====
The southern terminus of the GPT stands at the shore of Lago Viedma on the eastern edge of the Southern Patagonian Ice Field. There are attractive and suitable trails and packraft routes south of Lago Viedma but there are three logistical challenges that currently impede a feasible and continuous southern extension of the GPT without significant road walking:
* There is no ferry service over Lago Viedma. This lake is also far too wind-exposed and therefore to my current knowledge too dangerous to be packrafted.
* There is no legal border crossing between Argentina and Chile on the prospective routes (between Lago Argentino and Torres del Paine). There seems to be a legal way to apply for a special expedition permit but this seems utterly complicated and I know nobody who received such a permit.
* Hiking in Torres del Paine became very restrictive and requires i.e. reservations for camp sites that must be made several months in advance which is not practical for such an unpredictable long distance hike.
Overcoming these challenges is not impossible but attempting a continuous southbound extension makes out of an already very challenging long distance hike a bureaucratic and probably quite expensive expedition. An alternative is giving up continuity and bus around these obstacles without connecting footsteps.
I have an approximate route in my mind and I already reserved section numbers (GPT41 to GPT50) for this southbound extension to the most southern continental point of Americas: Cabo Froward. An extension of the GPT to Tierra del Fuego and Isla Navarino is also under consideration but crossing Tierra del Fuego will probably require substantial road walking. But for now this southbound extension is not on the top of my agenda. Before personally focusing on it I wish to consolidate the GPT between Santiago and Lago Viedma by investigating relevant optional routes and updating the trail documentation.
