This guide is designed for travelers like you, who are just starting to plan their trip and want trustworthy, useful, and in-depth information—something beyond the generic travel sites.

What Is the High Mountain Region of Mendoza and How to Get There

Mendoza’s high mountain zone stretches across the western edge of the province, from Potrerillos to the Chilean border.

Aconcagua Provincial Park: Nature at Its Purest

Aconcagua Provincial Park is the heart of high mountain Mendoza. It spans more than 70,000 hectares and protects glaciers, wetlands, and the highest peak in the Americas: the mighty Aconcagua at 6,962 meters (22,841 feet) above sea level.

But you don’t need to be a climber to enjoy it. There are several routes for different kinds of visitors:

• Laguna de Horcones: a short, well-marked trail suitable for all ages, offering stunning reflections of Aconcagua in the water, surrounded by silence and raw beauty.

• Confluencia: a moderate, 7-8 hour round-trip hike to the first base camp, offering a taste of the mountaineering world.

• Plaza Francia / Plaza de Mulas: multi-day treks for experienced hikers with overnight stays in organized camps.

• Bonete Summit: a high-altitude goal for those seeking adventure without attempting Aconcagua’s full ascent.

The official trekking season runs from November to March and requires permits depending on your activity. Outside of this period, the park is closed due to snow and extreme weather. To check forecasts and seasonal access, visit this detailed guide to high mountain weather.

In winter, while the trails are closed, you can still appreciate the park from National Route 7. Natural viewpoints near the park entrance offer excellent photo opportunities of the snow-covered peak and the vastness of the Andes—no entrance necessary.

Puente del Inca: History, Geology, and Living Legend

At 2,700 meters (8,858 feet) above sea level, Puente del Inca is more than a geological curiosity—it’s a place rich in history, legend, and cultural value. It’s a natural formation of travertine and mineral deposits that spans the Las Cuevas River and was used as a crossing by Indigenous peoples and General San Martín’s Army of the Andes.

In the 19th century, it became a thermal spa and railway station. Ruins of the old bath hotel are still visible today. Its natural and cultural significance earned it a nomination as a UNESCO World Heritage Site and made it part of a protected bi-oceanic corridor.

Walking on the bridge is no longer allowed to preserve it, but interpretive trails, viewpoints, and artisan stalls make it a fascinating stop.

Cristo Redentor Tour: A Symbolic Journey

The Cristo Redentor de los Andes stands at 3,832 meters (12,572 feet) on an international mountain pass once used by San Martín’s liberating army. Inaugurated in 1904 as a symbol of peace between Argentina and Chile, it remains one of the region’s most meaningful sites.

The road to the summit is open between January and March, and the journey—whether by guided tour or 4×4—offers panoramic views of Las Cuevas gorge, the northern face of Aconcagua, and snow-dusted valleys. It’s a trip that blends history, geography, and symbolism in one unforgettable experience.

Snow Parks: Winter Fun at Los Puquios and the Future of Penitentes

In winter, the landscape transforms into a snow-covered postcard. The most accessible family-friendly snow park is Los Puquios, just minutes from Aconcagua.

It offers sledding, beginner ski slopes, equipment rental, ski lessons, and snow play areas for kids. While not a traditional ski resort, it’s ideal for those who want a safe and simple way to enjoy the snow.

Nearby, the historic Penitentes Ski Resort—opened in the 1970s—has been closed since 2020. However, the provincial government has announced plans to convert it into a sustainable tourism site focused on year-round activities like hiking, nature tours, and high-altitude sports. It’s a project in progress with great potential.

High Mountain Flora and Fauna: Extreme Adaptation

At first glance, Mendoza’s high mountains may seem barren. But the biodiversity here is subtle and resilient, adapted to intense UV radiation, dry winds, and freezing temperatures.

Notable animal species include:

• Andean condor: the largest flying bird in the world, with a wingspan of up to 3 meters.

• Guanacos: camelids that roam in herds, grazing on mountain grasses.

• Red foxes, high-altitude lizards, chinchilla rats, and, in remote areas, the elusive puma.

Plant life includes coirón grasses, Andean verbenas, llareta cushions, high-altitude shrubs, and lichens. Each species blooms depending on elevation, sun exposure, and soil moisture. It’s a fragile ecosystem best appreciated with knowledgeable nature guides.

Living Andean Culture: Traditions of the Cordillera

This region has been inhabited for centuries by the Huarpe and Pazioca peoples and was later traversed by Argentina’s independence army. In Uspallata, you can still find Inca-era smelting ovens and local legends about hidden gold.

Today, high mountain culture lives on in festivals, traditional food, stories from local guides, and crafts passed down through generations. Many excursions include not just geographic insights, but oral history that connects visitors to the living heritage of the Andes.
