Nature and adventure

El Leoncito National Park

Located about 34 km from Barreal, this national park is famous for its hiking trails, natural beauty, wildlife, and exceptionally clear skies—ideal for astronomy and stargazing activities.

El Leoncito National Park aims to preserve different environments such as the puna and the pre-Andean region. The park features an interpretation center, a free camping area, and two walking trails: an easy 40-minute trail leading to a waterfall, and a more challenging trail lasting over two hours. Scenic viewpoints with excellent views are also available.

Wildlife in El Leoncito National Park: the most characteristic animals include guanacos, rheas (ñandúes or suris), foxes, pumas, maras, cavies, lizards, wildcats, skunks, armadillos, and an interesting variety of birds.

Another major attraction of El Leoncito National Park is its two astronomical observatories:

• El Leoncito Astronomical Observatory (C.AS.LEO): dedicated to measuring the intensity of starlight. It offers guided daytime visits (10:00–12:00 and 2:30–5:00 pm) and nighttime visits, and overnight stays are also possible.
• U. CESCO Astronomical Observatory: focused on studying the size of stars. It can be visited during the day (10:00–12:00 and 4:00–6:00 pm) and at night.

Mount Mercedario

At 6,770 meters high, Mount Mercedario is the natural sentinel of Barreal and an icon for mountaineering, trekking, and photography enthusiasts.

The most popular ascent route is the north face via the Ollada Glacier, though it is not the only option. From the east, climbers follow the Caballito Glacier route. The western ascent is more vertical and dangerous, known as the Argentina route. From the south face base camp, it is also possible to access other peaks of the Ramada Range: Pico Polaco (6,000 m), La Mesa (6,100 m), Alma Negra (6,200 m), and La Ramada (6,300 m).

All expeditions depart from the town of Barreal, where transportation, equipment, supplies, and certified guides can be hired.
