The Los Glaciares National Park

is located in the Argentine part of Patagonia (Santa Cruz Province). It is the largest national park within the country of Argentina and was declared a World Heritage Site by UNESCO in 1981. It is home to part of the Southern Patagonian Ice field and contains some of the region's largest and most breathtaking glaciers (including Perito Moreno Glacier& huge mountain lakes. In the north, Cerro Torre and Mount Fitz Roy’s jagged peaks rise above the mountain village of El Chaltén.

El Chaltén

was founded in 1985 as a border post with Chile and has since blossomed into a lively mountain village that is visited by thousands of trekkers, hikers and climbers every year. The dazzling little settlement serves as a "base camp" for day hikes in the northern part of the Los Glaciares National Park and, with its countless restaurants, pubs and small supermarkets, is the ideal place to recover from the hikes.


The best way to explore some of the more than 250 glaciers and the Patagonian Andes within Los Glaciares National Park is a four- or five-day journey that combines hikes to the

• Pinnacles of Mount Fitz Roy & Cerro Torre,

• Nature Reserve "Los Huemules"

• top of Loma del Pliegue Tumbado and

• the famous Perito Moreno Glacier and Lago Argentina, the largest lake in Argentina.

  • Loma del Diablo lookout, Reserve Los Huemules El Chalten

Which Are the Best Hikes in Los Glaciares NP?

  • Starting from the mountain village El Chaltén, day hikes to Mount Fitz Roy and Cerro Torre: You’ll explore the park’s northern region, hiking to "Laguna de los Tres" (the best viewpoint for Mount Fitz Roy), "Laguna Torre" (the best viewpoint for Cerro Torre) and the "Madre and Hija" lagoons.
  • The day hike to the Loma del Pliegue Tumbado lookout is one of the most impressive in the region and offers a unique opportunity to see Cerro Torre and Fitz Roy with their glaciers and lakes from one point (weather permitting). On the way back you can expect fantastic views of Lake Viedma with its intense turquoise blue.
  • Tackling the region’s famous trails into one longer adventure offers more opportunity to explore glaciers, valleys and the South Patagonian Ice Cap.
  • Travelers who choose a multi-day trek in Los Glaciares can veer away from the more crowded trails, as well as try mountaineering and ice trekking in some of the park’s most remote areas. Hike by day, then stay in a mountain campsite each evening, waking with sunrise views of the peaks and glaciers.

Are There Off-the-Beaten-Path Day Hikes?

  • Hikers seeking solitude in Los Glaciares will love the Los Huemules Nature Reserve, to the north of El Chaltén and bordering the park. The private reserve offers a number of trails of varying difficulty. The gentlest walks are Laguna Azul, Cagliero Glacier and the Electrico Valley, while Loma del Diablo lookout hike is a bit more challenging.
  • Wildlife is abundant in the reserve, including Magellanic woodpeckers, condors, puma and, of course, the Huemules (Andean deers). The hikes here are suited to those who want a quiet nature experience to complement the spectacular (and more crowded) Laguna de Los Tres and Laguna Torre treks they might take on other days.

Why should I book with a local agency?

A local Los Glaciares National Park tour operator, like MOSER Active, can provide peace of mind, thanks to their experience and expertise in the region, as well as guides who have spent hours on the same trails you will hike. In addition, a local agency can provide porter service to assist on your trek and, should the need arise, are able to provide emergency assistance and first aid. Choosing a local travel agency also supports the community you are visiting and promotes mindful travel practices.
