Sierra de las Quijadas National Park
Park Argentine national park with dramatic red rock canyons
Red sandstone canyons and fossil-bearing badlands in San Luis Province draw hikers, photographers and geology buffs to Sierra de las Quijadas National Park, where trails cross exposed strata, ravines and desert-adapted birdlife.
Sierra de las Quijadas National Park is a protected area in San Luis Province, Argentina, notable for its red sandstone badlands, deep canyons and exposed geomorphology. The park is recognised for its paleontological and geomorphological importance within central Argentina.
The landscape features steep cliffs, eroded ravines and scattered scrub typical of an arid interior environment. Visitors follow short trails and viewpoint tracks to see canyon walls, layered rock formations and fossil-bearing outcrops.
The area was set aside for conservation to protect its distinctive landforms and fossil sites and has been the subject of scientific study and guided visits. Human impacts have been limited by the park’s remote inland location and by restrictions on off-trail travel.
The park lies in northwestern San Luis Province in central-west Argentina, inland from the Atlantic-facing lowlands and separated from major coastal cities; the nearest provincial centres are the primary reference points for access and logistics.
- Best time to visit: Conditions are arid and exposed in summer, so spring and autumn are generally more comfortable for hiking and canyon viewpoints.
