The climbing-town basecamp for Fitz Roy and Cerro Torre. Founded in 1985 as a border-dispute settlement, free-entry into Argentina's Los Glaciares north sector, walk-from-your-door trailheads. The reframe, the permits, the weather windows, and the one circuit that actually earns the word 'serious'.
Torres del Paine
LiveThe W, the O, Paine Grande, Grey Glacier
The Torres del Paine W trek and O circuit — Chile's paid-circuit Patagonia, CONAF-administered, with Vertice and Las Torres Patagonia as the two private refugio operators. The booking system is the crux, not the walking: three separate portals, and the May 1 2026 CONAF fee overhaul that most guides haven't caught. Every claim sourced.
