The reserve is open every day of the year from sunrise to sunset, approximately from 8:00 a.m. to 6:00 p.m. in high season, although it is recommended to check weather conditions. To get there, access is via Provincial Route 173 in San Rafael, Mendoza; if you are driving, take the turnoff from the city, or use public transportation to San Rafael and then a taxi. More details are available on the official Mendoza Tourism website.
Admission is free for all visitors, as it is a protected provincial nature reserve. However, if you hire guides or excursions, additional fees of around 500-1000 ARS per person may apply. Check the official website for updates to confirm exemptions or parking charges.
It is recommended to spend at least 2-3 hours exploring the main trails and enjoying the views, but if you take longer hikes, it could extend to half a day. Include time for photos and breaks at the birdwatching areas. It is ideal for a morning visit to avoid the midday heat.
This reserve, located in Mendoza, protects unique geological formations of mogotes and canyons formed millions of years ago by erosion, with an ecosystem rich in endemic flora and fauna such as condors and guanacos. Culturally, it is significant for the Huarpe Indigenous communities who once inhabited the area, highlighting its value in preserving Argentina’s natural heritage.

The best time is during spring (September-November) or autumn (March-May), when the weather is mild and there are more wildflowers, avoiding the intense summer heat. Visit early in the morning for better visibility and fewer crowds, ideally between 9:00 a.m. and 11:00 a.m. Check local forecast apps for unexpected winter rain.
The main trails have accessible sections with paved or gravel paths for wheelchairs, but the higher areas require moderate hiking and are not recommended. There are adapted viewpoints near the entrance; contact the visitor center at +54 2627 42-3000 for assistance or alternative routes. Accessibility improvements are ongoing according to provincial reports.
Nearby, in San Rafael, you can visit Atuel Canyon just 20 km away, ideal for rafting and spectacular views, or Valle Grande with its reservoirs for picnics. Do not miss the wineries along Mendoza’s wine route, about 30 minutes away by car. For more ideas, explore the San Rafael Tourism website.
Bring water, sunscreen, and comfortable hiking shoes, as the terrain can be uneven; also insect repellent in the warm season. Respect the rule of leaving no litter and keep your distance from wildlife; consider joining a guided tour to learn more about the biodiversity. If you are traveling with children, choose short routes and check the weather on the official website before heading out.
