On the southern edge of the San Rafael department, along Route 40 or 144, you’ll find a small town called "El Sosneado," which serves as the gateway to a circuit of breathtaking Andean landscapes.

It is recommended to travel this road in high-clearance vehicles, as there are several streams to cross and the road conditions are often poor.

The circuit follows the Atuel River from its source at the Atuel Lagoon to the town of El Sosneado. Along the way, you'll witness stunning scenery featuring volcanoes, lagoons, rivers, and valleys.

Among the popular activities in the area, trekking, fishing, and horseback riding stand out. Some points of interest include:

Salinas del Diamante: Located along Route 144 before reaching El Sosneado, this is a massive open-pit salt mine.

Volcán Diamante: A diamond-shaped volcano situated on Route 40 before reaching El Sosneado.

Laguna El Sosneado: A lagoon at the base of Cerro Sosneado, ideal for fishing and birdwatching.

Cerro Sosneado: The southernmost mountain in the Andes that exceeds 5,000 meters above sea level. Its beauty and grandeur are truly awe-inspiring.

Hotel Termas del Sosneado: The ruins of an old hotel that operated until 1953, featuring an impressive stone structure alongside ancient thermal pools.

Atuel Lagoon and Waterfalls: At the foot of Volcán Overo, you’ll find the Atuel Lagoon, the source of the Atuel River. Just a few meters away are the famous waterfalls that feed into the lagoon.
