Pampa del Leoncito, High-altitude plain in San Juan Province, Argentina.

Pampa del Leoncito is a high-altitude plain in San Juan Province that stretches flat and dry across several kilometers. The surface displays a distinctive white color marked by pentagonal cracks formed when an ancient lake dried up over millions of years.

The region was home to early cultures like the Fortuna and Morrillos peoples, whose presence dates back approximately 8,500 years. These first inhabitants established settlements that marked the beginning of human activity in this highland area.

Indigenous groups left behind rock carvings and painted caves that still cover the area, showing how deeply connected ancient peoples were to this highland. These artworks remain visible today and offer a window into their spiritual and daily life.

The flat and hard surface here is ideal for special activities like land sailing, which is possible during most seasons. Visitors should prepare for dry conditions and minimal shade, making proper gear and sun protection essential.

The white pentagonal cracks covering the entire surface were not formed by normal erosion but resulted from the drying of an ancient lake. This geological pattern creates a natural mosaic that looks particularly striking when viewed from a distance.
