When to Visit El Chalten

You can visit El Chalten all year round, but when is the best time to visit El Chalten?

Weather-wise the hiking season is in the summer months from October to April, with the best weather from December to March with higher temperatures. It can however get very windy in summer and this is the peak tourist season with higher prices. Camping in strong winds is challenging. 

Shoulder season, November and April, is good to avoid the crowds and temperatures are nice for hiking. It is however a bit of a gamble, can be great, but you can have bad luck with wind, rain, and cold weather.

In winter between June and September, it can be cold, the wind is less, but the trails can be inaccessible because of snow.

Camping in El Chalten

Some of the most popular campsites in the town of El Chalten can be seen below, see our article on Camping in El Chaten for a review of the sites and camping in the region.

Accommodation in El Chalten

  • El Chalten has accommodations to suit all tastes and budgets. If you are hiking in season, I would strongly advise that you book accommodation ahead. We loved camping here, but it is fantastic to return to a warm lodge, and have your own bathroom and a comfortable bed after a long day hiking in the chilly Patagonian weather!
  • Super comfort  Hostería El Pilar, fantastic spot, country house 17 km from El Chalten
  • .Los Cerros Boutique Hotel & Spa, a beautiful boutique hotel close to the trails
  • Destino Sur Hotel & Spa de Montaña – 5-star luxury hotel, with excellent ratings
  • Mid Budget – Hosteria El Paraiso Alpine-style cabins, nice views. Good value for money.

El Calafate has the nearest airport, about 220km away, and can be reached from Buenos Aires by plane or bus. The road between El Calafate and El Chaltén is paved in excellent condition and the trip takes 3 hours by bus. There is a daily bus between El Calafate and El Chaltén works all year round, twice per day morning and evening (3 times in the peak season).  Chalten Travel is a popular bus service to use.

Buses are quite expensive and people try hitchhiking. If you decide to hitchhike, just get on the road early, we had a long day of very competitive hitchhiking here. We hitchhiked a lot in Patagonia and it was a great way to explore the area and to travel the Carretera Austral.
