Parque Nacional Sierra De Las Quijadas

Stretching across the arid heart of San Luis province, Parque Nacional Sierra De Las Quijadas is a dramatic landscape of red-rock canyons, fossil-rich badlands, and desert silence. This lesser-known gem rewards travellers who venture off the beaten path with raw, otherworldly beauty and a palpable sense of isolation. The park protects a slice of the Sierra de las Quijadas range, where wind and water have sculpted jaw-like formations (hence the name) and exposed dinosaur-era fossils. It’s a paradise for hikers, photographers, and anyone craving an authentic encounter with Argentina’s wild interior.

Highlights & What to See

• Potrero de la Aguada – The park’s main canyon, a stunning amphitheatre of red sandstone cliffs. Hike the Sendero de la Aguada loop (about 2 hours) for panoramic views and a chance to spot guanacos and condors.
• Fossil Trail (Sendero Paleontológico) – A short, interpretive walk past dinosaur footprints and petrified wood, offering a tangible link to the Cretaceous period.
• Mirador del Cóndor – A viewpoint perched high above the canyon where Andean condors often ride thermals. Best visited in the early morning or late afternoon.
• Río Seco – A dry riverbed that transforms into a temporary lagoon after rains, attracting birdlife. The stark, cracked mudflats create surreal photo opportunities.
• Night Sky – With minimal light pollution, the park is a stellar spot for stargazing. Bring a red flashlight and a blanket to lie back and watch the Milky Way.

Suggested Time to Spend

Most visitors explore the park in a full day, arriving early to tackle the main hike before the midday heat. If you’re short on time, a half-day allows you to visit the interpretive centre, walk the Fossil Trail, and drive to Mirador del Cóndor. For a deeper experience, camp overnight at the designated campground (no facilities) to catch sunrise over the canyon and enjoy a second day of hiking. Remember to bring ample water, sun protection, and a full tank of fuel – the nearest services are in the town of San Francisco del Monte de Oro, about 40 km away.
