Sierra de las Quijadas, Argentina’s Best Fossils, Canyons & Martian Landscapes (2026)
While crowds flock to the more famous Ischigualasto (Valley of the Moon) 200 kilometers north, Sierra de las Quijadas National Park delivers a more intimate, raw, and geologically profound encounter with Argentina’s prehistory. Here, a staggering 120 million years of Earth’s story are etched into crimson cliffs and labyrinthine canyons, yet you’ll often share the 73,000-acre park with just a handful of other explorers. This is where the silence is deafening and the landscapes feel truly alien.
Why Sierra de las Quijadas, Argentina Stands Out

- Historic Architecture: Not man-made, but nature’s own: the Potrero de la Aguada, a colossal, 4,000-hectare natural amphitheater of layered red rock, sculpted over eons by wind and water.
- Cultural Scene: The ancient Huarpe culture, whose rock art and artifacts found within the park connect you directly to the region’s first inhabitants over 1,500 years ago.
- Local Specialties: A hearty Patagonian lamb *asado* (barbecue) at a nearby *estancia*, the quintessential post-adventure meal in San Luis province.
Pro Tip: The park is at its most magical and manageable in the shoulder seasons. Aim for March to May or September to November. Daytime temperatures are pleasant for hiking (20-25°C / 68-77°F), the light is perfect for photography, and you’ll avoid the intense summer heat that can exceed 40°C (104°F) and the occasional winter chill.

Planning Your Trip: Practical Essentials
Getting There and Around
- By Air: The nearest major airport is Ingeniero Aeronáutico Ambrosio L.V. Taravella International (COR) in Córdoba, a 4-hour drive away. Aerolíneas Argentinas and low-cost carriers like JetSMART and Flybondi serve it. From there, you must rent a car. Book flights at Skyscanner for best deals.
- By Train: No direct train service exists to the park. The region is best accessed by road. For long-distance travel within Argentina, reserve tickets at Trainline or the national railway website.

- Local Transport: There is no public transport to or within the national park. All exploration is done via private vehicle or on foot from the visitor center. Organized tours from San Luis are available but infrequent.
