Sights and Recreation

Las Quijadas’s most unforgettable sight is the natural amphitheater of Potrero de la Aguada, where the last 25 million years of runoff—from precipitation that now averages only 300 millimeters per annum—has eroded ancient sediments to expose bright sandstone beds and conglomerates to the west. An easy trail follows the Aguada’s rim toward the south for about half an hour, but hikers should refrain from descending into the intricate canyons without plenty of water, high-energy snacks, and an obligatory local guide.

Along the gravel road to Potrero de la Aguada, stop at the recently excavated Hornillos Huarpes, the ovens where the park’s pre-Columbian inhabitants prepared their meals and fired their ceramics. These have been carbon-14 dated at about A.D. 1000.

Practicalities

About one kilometer east of the Potrero de la Aguada overlook, there’s a free APN campground with clean flush toilets as well as a small grocery with snacks and cold drinks.

There’s still no formal visitors center, but rangers at the park entrance (who collect a US$7 admission for foreigners, US$2 for Argentine residents) provide maps and can answer questions. At the campground, local guides offer several reasonably priced (around US$7–10 pp) 3–4-hour hikes into the badlands, though none of them can manage English.

Spanish-speaking visitors to San Luis should look for the self-published guidebook El Parque Nacional Sierra de las Quijadas y Sus Recursos Naturales by English-speaking geologist David Rivarola (tel. 02652/15-54-3629, rivarola [at] unsl [dot] edu [dot] ar, www.lasquijadas.com), who offers the most informative park tours, but because of time demands only does so for large groups and for foreigners in particular.

Buses between San Luis and San Juan can drop passengers on the access road just north of the hamlet of Hualtarán. Travel agencies in San Luis sometimes organize day tours.
