Los Glaciares National Park is a vast UNESCO-listed wilderness in Argentine Patagonia, where sharp granite peaks tower over turquoise lakes, and ancient glaciers cover the landscape. The most famous of these is the Perito Moreno Glacier, which juts out into Lago Argentino (the country’s largest lake), where icebergs calve thunderously into the water.
“The park protects the Patagonian Ice Field, which is a very big mass of ice with a lot of glaciers that we share with Chile,” says Agata West, who works in adventure travel and lives in Patagonia.
The Patagonian Ice Field also includes serrated mountains such as the spiky Cerro Fitz Roy (3,405m/11,171ft) and needle-like Cerro Torre (3,128m/10,262ft), which rise sharply upwards from the surrounding ice. Surrounding the ice you’ll find patches of old growth forest and swathes of Patagonian steppe, rocky shrub-studded plains unique to the region.

“You have two main entrances to the national park. The north can be accessed from the small town of El Chaltén, which we call the trekking capital of Argentina, because from the door of your hotel you can do hundreds of hikes,” says Agata. “We have these beautiful, famous hikes to see Mount Fitz Roy and Cerro Torre.
“The closest town to the south entrance is El Calafate, which is where you can access the park’s highlight, Perito Moreno Glacier. So El Chaltén is where you go for trekking, and El Calafate is where you go to do glacier excursions.”

Where is Los Glaciares National Park Located?
Los Glaciares National Park is in the southwest of Santa Cruz Province, within the Argentine section of Patagonia. It borders Chile to the west and is part of the Southern Patagonian Ice Field. It covers an area of 2,806 square miles (7,269 sq. km).
Iconic Sights and Landscapes in Los Glaciares
Perito Moreno Glacier
Perito Moreno Glacier is one of the highlights of Los Glaciares National Park—a glacier with an area of 155 square miles (250 sq. km), which flows into the vast Lago Argentino. It’s one of the reasons why Los Glaciares National Park received a UNESCO designation.
“The overwhelming beauty of the landscape is epitomised where the Perito Moreno Glacier meets Lake Argentino,” the UNESCO description reads. “The vast front of the slowly and constantly moving glacier, up to 60 metres (197ft) high, regularly calves bluish icebergs into the waters of Lake Argentino, an audiovisual spectacle attracting visitors from all over the world.”
Opposite the glacier there are around three miles (five km) of wooden boardwalks, with viewpoints overlooking the ice. Boat trips and glacier trekking allow you to get even closer to Perito Moreno.
Lago Argentino
Lago Argentino is the largest freshwater lake in Argentina, spanning over 566 square miles (1,465 sq. km), and it forms the aquatic heart of Los Glaciares National Park. It’s fed by meltwater from the Perito Moreno, Upsala, Spegazzini and Onelli Glaciers.
Boat excursions across Lago Argentino provide a front-row seat to some of Patagonia’s most dramatic scenery, including icebergs, hidden coves, and towering glacier walls. It’s also a hub for birdlife, including black-necked swans and flamingos, the latter of which can be seen in Reserva Laguna Nimez near the town of El Calafate.
“El Calafate is located very close to Lago Argentino, and it’s very nice to go for a stroll along the lakeshore,” Agata says.
Mount Fitz Roy
Mount Fitz Roy (also known as Cerro Fitz Roy) has a jagged granite summit which rises above the Patagonian steppe, reaching 3,405m (11,171ft) into the sky. It is one of Patagonia’s most recognisable landmarks, often cloaked in a crown of clouds. In fact, its sharp silhouette inspired the logo of the outdoor brand Patagonia.
First climbed in 1952, Mount Fitz Roy is popular with experienced mountaineers. For those without technical mountain climbing skills, hiking trails such as the Laguna de Los Tres hike offer excellent views of its jagged summit.
It’s beautiful when you descend to the lake and see Mount Fitz Roy in front of you
“It’s beautiful when you descend to the lake and see Mount Fitz Roy in front of you,” Agata says. “Of course, you need good weather because if not, Fitz Roy is covered by clouds.”
Cerro Torre
Cerro Torre is located near Fitz Roy, a sharp peak towering to 3,128m (10,262ft). Although it’s shorter than Fitz Roy, it’s the harder climb, with its vertical walls and ice-covered summit.
From the town of El Chaltén, there are numerous hiking trails offering views of this spectacular peak. The Laguna Torre hike is considered to have one of the best vantage points, taking you to a glacial lake with the peak reflected in its waters.
Adventure Activities
Hiking
There are plenty of opportunities for hiking in Los Glaciares National Park, from multi-day treks into the backcountry (a guide is recommended), to shorter half-day hikes which can be done independently.
Amongst the most popular walking spots are the Perito Moreno Glacier Walkways. These walkways are comprised of a 2.9 mile (4.7km) network of wooden boardwalks, stairs and well-maintained trails on the opposite shore of Perito Moreno Glacier, colour-coded according to difficulty level. You'll have excellent views of icebergs calving into the water below.
If you're looking for something more challenging, base yourself in El Chaltén. One of the most popular accessible from here is the Laguna de Los Tres Hike, also known as Sendero Fitz Roy. It's a 12.4 mile (20km) out-and-back route. The route takes you through the De Las Vueltas River Valley, up through groves of Antarctic beech trees (ñires) and across rocky moraine to the Laguna de Los Tres, a trio of glacial lakes where you have one of the best views of the iconic Mount Fitz Roy.
“The good thing about Laguna de Los Tres is that the route is beautiful and there are lots of viewpoints along the way. So you don’t have to complete the whole 20-kilometre-long hike if you don’t want to, or if the weather worsens,” Agata says.
Glacier Trekking
Perito Moreno Glacier offers opportunities for glacier trekking. There are two options: the ‘Minitrekking’ which lasts around 90 minutes, or the ‘Big Ice Tour’, where you’ll be on the ice for around three hours, and trek through the Andean forest next to the glacier for a further four. You’ll marvel at the glacier’s deep crevasses, brilliant ultramarine lagoons and subterranean ice caves.
Both hikes require you to wear cold weather clothing and crampons. You will also need to be accompanied by an experienced local guide.
Kayaking
The glacier-fed rivers and lakes within the reserve, making Los Glaciares National Park an ideal spot for kayaking. Best-known is Lago Argentino, the largest freshwater lake in the country. Launch from Redonda Bay near El Calafate, and you can explore this vast body of water.
The Perito Moreno Glacier also juts out into Lago Argentino. There's a launch site near the Perito Moreno boardwalks, enabling you to paddle close to the vast northern face of this sublime glacier.
Another option is to paddle in the La Leona River, located in the eastern part of the park. The launch point is north of El Calafate. You'll follow the river southwards as it carves a path through the wild steppe. There'll be the opportunity to beach your kayaks and hike to the Cerro Los Hornos, a viewpoint studded with petrified trees and dinosaur fossils, surrounded by antediluvian folds of rock.
Boat Tours
Boat tours give you the opportunity to see the national park’s glaciers up close and personal. Excursions across Lago Argentino, the country’s largest lake, are particularly popular. Board a small boat near Perito Moreno glacier and sail close to its face. You can then head down the Canal de los Témpanos, a channel studded with the icebergs that have calved from the main glacier.
Full-day boat trips across Lago Argentino are also possible, exploring the Patagonian Ice Field as you visit the Spegazzini, Upsala and Perito Moreno Glaciers.
Wildlife Watching
For Agata, the wildlife is one of the highlights of Los Glaciares national park.
“You can see a lot of guanacos, a lot of rheas and there are chances to see the puma, which is a beautiful animal,” she says. “I’ve seen pumas many times—I even saw a puma eat a guanaco, which was quite impressive.”
While it is possible to go on a dedicated wildlife watching tour, you’ll also see wildlife while doing other activities, such as kayaking or trekking—or simply driving across the steppe.
Where to Stay
Agata recommends splitting your time between El Chaltén in the north of the park, and El Calafate in the south. A few nights in each region will allow you to enjoy Los Glaciares’ main highlights.
El Chaltén
El Chaltén is a small town of around 3,000 inhabitants, situated in the northern part of Los Glaciares National Park. It’s known as the Trekking Capital of Argentina, and is surrounded by dramatic mountainscapes.
“It's nice because you can go from the door of your hotel to the main trails, and you’re also within walking distance to its bars and restaurants,’” Agata says. “It’s not a city like El Calafate, but has the spirit of a mountain town.”
El Calafate
El Calafate is located 29.5 miles (47.5km) east of the southern entrance to Los Glaciares National Park, and is the gateway town for visiting Perito Moreno Glacier. It’s easy to arrange transportation into the park or a glacier trekking tour from here.
For dinner, I like Mi Rancho. It's a very traditional, cosy restaurant. And for going out to have a beer, I like Shackleton Solo
“There are 30,000 people living here, and it's more active during winter than El Chaltén, although it's not a winter destination because here we don't have snow,” Agata says.
“For dinner, I like Mi Rancho. It's a very traditional, cosy restaurant. And for going out to have a beer, I like Shackleton Solo. There are often DJs or live music there, and it has a view of the lake.”
