This pretty much shows everything I'd like to see while down there. https://www.youtube.com/watch?v=GCFyot7FKr4
Update: Six weeks, over 1500kms, more than 10 bus rides, hitch hiking, hiking my arse off on every trail I could, in more than 5 national parks. From Pucon, to Puerto Montt, through Chiloe, across to Puerto Cisnes by Ferry, up to Puyuahuapi, down to Coyhaique, Rio Tranquilo, Cochrane, Coleta Tortel, back to Cochrane, to Villa O-Higgins, Ferry to Candellario Mancia, hike to Argentina, another ferry across Lago del Desierto, to El Chalten, bus to El Calafate and Puerto Natales, another bus to Punta Arenas, and flight back to Santiago. I'd do it all again tomorrow for such an incredible experience, warts and all.
