Argentina offers hiking experiences across very different landscapes, from the colorful mountain valleys of the northwest to Patagonia’s glaciers and the southern forests of Tierra del Fuego. Some routes are short and accessible, while others require several days, careful preparation and a substantial budget.

The following seven options offer a useful starting point for planning a walking holiday, with approximate costs in euros.

Quebrada de Humahuaca: Colorful Valleys

In northwestern Argentina, Quebrada de Humahuaca is known for its layered mountains, deep ravines and striking geological formations. The valley stretches for approximately 155 kilometres, giving visitors plenty of opportunities to enjoy its scenery on foot.

There is no single route that defines the area. Walks can range from a relaxed half-day outing to a longer day exploring the surrounding countryside. There is no general entrance fee for walking in the valley. Travelers should budget around €15–€40 for local transport and optional guiding, depending on the distance and arrangements.

Paseo Superior: Iguazú Falls

For an easier walking experience, Paseo Superior in Iguazú National Park is an excellent choice. This approximately 1.9-kilometre circuit follows elevated walkways through lush subtropical surroundings, offering views across the upper sections of the famous waterfalls. The route is mostly flat and usually takes between one and three hours. The international visitor entrance fee is approximately €36 per person.

Cerro Aconcagua: A Serious Challenge

Standing at 6,962 metres, Cerro Aconcagua is the highest mountain in the Americas. Located in Mendoza Province, it attracts experienced hikers who want to attempt a major high-altitude journey. The Normal Route covers approximately 40 kilometres and usually requires 13 to 15 days.

Aconcagua requires an official climbing permit, and the price depends on the season, route and visitor category. Guided expeditions can cost several thousand euros, so this is a considerably more expensive option than an ordinary day hike. Check the current permit tariff before making arrangements.

Nahuel Huapi: Overnight Mountain Walks

In Argentina's Lake District, Nahuel Huapi National Park is a rewarding destination for travelers who enjoy longer walks and overnight stays. Its mountain landscape includes forests, lakes, rocky slopes and established trekking routes. One popular option leads towards Refugio Emilio Frey near Cerro Catedral. Another is Paso de las Nubes, a two-day journey through changing mountain scenery, with an overnight stay at Refugio Agostino Rocca. Both routes require suitable footwear and preparation for changing weather.

The general international visitor entrance fee is approximately €21 per day. Reserve overnight accommodation ahead of time, particularly during busy travel periods.

Laguna de los Tres: Fitz Roy Views

Starting from El Chaltén in Patagonia, Laguna de los Tres is one of Argentina's most memorable day hikes. The round trip is approximately 20–25 kilometres, depending on the route measurement, and usually takes eight to ten hours. The trail passes through forested sections, open meadows and scenic viewpoints before reaching a beautiful mountain lagoon beneath Cerro Fitz Roy. The final climb is steep, so a reasonable level of fitness is important. Clear weather also makes a significant difference to the views.

The route is inside Los Glaciares National Park. The general international visitor entrance fee is approximately €30 per day. Transport, meals and accommodation in El Chaltén are separate expenses.

Perito Moreno Glacier: Walking on Ice

Near El Calafate, Perito Moreno Glacier offers a different kind of outdoor adventure. Rather than following a conventional mountain path, visitors can join an organized ice-walking excursion. The experience begins with a boat transfer across the lake, followed by a guided walk on the glacier using specialist equipment.

The activity is generally offered as a half-day experience, although the complete excursion takes longer when transfers and preparation are included. The Los Glaciares entrance fee is approximately €30 per person per day under the general tariff.

Tierra del Fuego: Southern Trails

At the southern end of Argentina, Tierra del Fuego National Park offers several walking routes that can be completed within a day. Its scenery includes forested slopes, open ground, lakes and coastal viewpoints. Senda Costera is an appealing option for visitors who want a longer walk, covering approximately eight kilometres along the shoreline. The international visitor entrance fee is approximately €24 per day.

Argentina has hiking routes for a wide range of interests and experience levels. Paseo Superior is suitable for a relaxed outing, while Quebrada de Humahuaca offers flexible walks through colorful valleys. Travelers seeking longer adventures can consider Nahuel Huapi or Laguna de los Tres, while Aconcagua requires serious preparation and a larger budget.
