Sierra de las Quijadas National Park

Carved from rust-red sandstone and scrubby bush, Sierra de las Quijadas National Park is one of Argentina's most dramatic landscapes. Its name—'jawbone range'—comes from the serrated ridge that dominates the horizon, a crumbling fortress of rock that shifts from ochre to violet as the sun arcs across the sky. This is raw, untamed nature: a place where the earth's layers are exposed like an open book, and the silence is broken only by the cry of a condor or the rustle of a mara. For self-drivers, it’s a thrilling detour off Ruta Nacional 147, offering a glimpse into a world that feels prehistoric.

Highlights & What to See

• Potrero de la Aguada – the park's centrepiece, a vast natural amphitheatre ringed by sheer cliffs. The short walk to the mirador (viewpoint) reveals a sea of red rock and, with luck, the endangered Andean condor circling overhead.
• Sendero del Cóndor – a 1.5-km trail that leads to a cliff-edge lookout where condors ride thermals. Go early for the best light and bird activity.
• Huellas de dinosaurios – near the park entrance, clear dinosaur footprints are preserved in ancient mudstone. It’s a quick, humbling stop that sets the tone for the park’s deep time.
• Flora and fauna – keep an eye out for guanacos, maras (Patagonian hares), and the rare picky choique (a flightless bird). The park is also a stronghold for the endangered retamo shrub, which carpets the valley floors in yellow during spring.
• Sunset at the Mirador de la Aguada – as the sun drops, the red rock glows like embers. Bring water and a jacket; the temperature plummets fast.

Suggested Time to Spend

Most visitors spend a full day: arrive early (the park opens at 8am), tackle the main trails by midday, and picnic among the cacti before driving the scenic loop. If you’re a keen hiker or photographer, consider two days—the light changes dramatically, and the longer trails (like the 8-km circuit to the far canyon) reward those with time. Overnight stays are limited to the basic campground near the ranger station; book ahead in high season (spring and autumn).

Nearby Areas Worth Combining

• San Luis – the provincial capital, 120 km south, offers good restaurants and a colonial plaza. It’s a natural base for stocking up on supplies before heading into the park.
• Merlo – a charming mountain village 200 km west, known for its microclimate and walking trails. Combine with the park for a varied road trip through the Sierras de los Comechingones.
• Laguna de la Niña Encantada – a small turquoise lake near Merlo, perfect for a refreshing dip after the park’s dusty trails.
• Ruta Nacional 147 – the drive itself is an attraction, cutting through the arid plains with views of the sierra. Stop at the roadside paradores for empanadas and local wine.
