Villavicencio is one of the most atmospheric short trips from Mendoza. The nature reserve protects a large area of mountain scrub and high desert in the foothills of the Andes, about an hour and a half from the city, and its main road is famous for a series of tight switchbacks, called the Caracoles, that climb steeply up the slope on an old gravel route. At the top are wide views over the valley, a quiet landscape of rock, thorn and sky and, if you are lucky, guanacos grazing on the slopes and condors riding the air currents. The reserve is also known for a grand old hotel, now a ruin, that was once a destination for spa guests and became tied to a well-known brand of mineral water. A half-day tour with a guide takes you up the gravel road, explains the area's natural history and stops for walks and photographs. The experience we link is a half-day adventure to the reserve, an inexpensive way to see the mountains without a full day on the road.
What you will see
The landscape changes quickly as the road climbs. Near the entrance there are shrubs, cacti and dry creek beds, and higher up the vegetation thins into rocky slopes and open grassland where wildlife is easier to spot. Guanacos, relatives of the llama, are the most common large animals, and Andean condors sometimes soar overhead. The views from the top look back over the plain toward Mendoza and across the foothills to the high peaks. A guide helps with the natural history and the story of the old hotel and the springs.
Planning the trip
Access to the reserve is controlled, and the gravel road is narrow and steep, so most visitors go on a guided tour that handles the permits and the driving. Half-day trips are the usual choice, and some operators run longer 4x4 versions or combine the reserve with the high-mountain road toward Uspallata. Check the weather before you go, because rain or snow can close the road, and expect cooler temperatures at altitude even on warm days. Opening arrangements can change, so ask the operator for current details.
Practical tips
Wear sturdy shoes, a warm layer and sun protection, and bring water and a camera. The altitude is moderate but noticeable for some people, and the drive on gravel can be bumpy for anyone prone to motion sickness. The reserve suits nature lovers, photographers and anyone who wants a taste of the Andes without the long drive to Aconcagua.
It also fits neatly into an afternoon, which makes it a good pairing with a morning wine tasting or a late-afternoon walk in the city. Prices depend on the length of the tour and the vehicle, and private 4x4 options cost the most.
Who it suits
The reserve is a good choice for anyone who wants a taste of the mountains without committing to a full-day expedition. Photographers love the light on the switchbacks, birdwatchers may spot raptors, and families with children who enjoy being outdoors will find it more engaging than another winery. It is also a sensible rainy-season alternative when the high road to Aconcagua is uncertain, though weather can affect both.
