El Chaltén is Argentina's trekking capital, a small town built at the trailheads beneath Fitz Roy and Cerro Torre in Los Glaciares National Park. The best part: the hiking is free — there's no park entrance fee and every trail starts on foot from town. Plan 3–5 days to do the main routes well. It's the easiest world-class trekking access in Patagonia.
The Huemul Circuit (4 days, advanced, with Tyrolean rope crossings and the Southern Patagonian Ice Field view) is the serious objective. Fit hikers can also string Fitz Roy and Torre into a camping loop over 2–3 days.
Fly Buenos Aires → El Calafate (FTE), then a ~3.5 hour bus to El Chaltén. The bus is scenic and reliable; book ahead in peak season.
October–April, with December–February warmest and busiest. November and March offer good weather with fewer people. Fitz Roy is famously shy — build in spare days to wait out cloud.
Layers, a windproof shell, broken-in boots, plenty of water capacity and snacks. Day hikes don't need camping gear, which keeps packs light.
They're not the same place. El Chaltén = trekking (Fitz Roy, Cerro Torre). El Calafate = glaciers (Perito Moreno) and the airport. Most itineraries pair them — see our Perito Moreno glacier guide.

A minimum of 3 days to do the two main hikes (Laguna de los Tres and Laguna Torre), or 5 days to add Pliegue Tumbado and a rest/weather day.
Yes — there's no park entrance fee, and all trailheads are reachable on foot from town.
It's about 25 km round trip over 8–10 hours with ~750 m of gain; the final climb to the lagoon is steep. Good fitness helps, but no technical skills are required.
