The Atuel Canyon is the headline natural attraction of southern Mendoza province and one of the most spectacular drives in the region. The canyon lies near San Rafael, a few hours south of Mendoza city, where the Atuel River has carved a winding gorge through layered rock, leaving smooth, colourful walls in shades of red, ochre and grey. The road runs along the canyon and past reservoirs, with viewpoints, rock formations and, in the warm months, a chance to stop for water activities in the Valle Grande area. A full-day tour from Mendoza takes you south by minibus, stops at viewpoints and a lunch spot, and returns in the evening. The experience we link is a full-day excursion from Mendoza to the canyon and Valle Grande, a convenient way to reach a region that is hard to cover with public transport. It is a long day, with several hours on the road, but the scenery is a striking change from the vineyards and the high peaks, and it gives a sense of how big and varied Mendoza province really is.
Why go
The Atuel Canyon is the most dramatic landscape in the south of the province, and it is easier to enjoy on a tour than by yourself. The river drops through the gorge, and the canyon road passes several lakes and dams where the water turns a deep green.
Along the route you can see rock formations that have been eroded into odd shapes, and the Valle Grande area is a hub for rafting, kayaking and other activities during the warm months. The region around San Rafael is also wine country, with a more relaxed feel than the valleys near Mendoza city.
Planning
This is a very long day, often twelve hours or more, with about three hours or more each way by road, so start early and bring snacks and layers. Because the trip is tiring, it works best for travellers who enjoy road trips and scenery rather than those who are short of time.
Some visitors prefer to stay overnight in San Rafael to see more of the canyon and the surrounding vineyards, which turns a marathon into a comfortable two-day trip. Check the weather and the season when booking, since winter conditions and water levels affect which activities are available.
Practical tips
Wear comfortable clothes and shoes, bring a hat and sunscreen and carry water. Water activities in the Valle Grande area usually cost extra and are weather and season dependent. Prices for the day tour are low compared with winery days, but food and activities add up, so budget for lunch and any optional extras.
The trip suits travellers who have already seen the main wine districts and want a change, as well as those who love landscapes and geology. If you only have a short stay in Mendoza, you may prefer to spend the time in the Uco Valley or the high Andes instead.
Who it suits
This trip rewards patient travellers who enjoy geology, driving and wide-open scenery, and who have already ticked off the main sights around Mendoza city. It is not the right choice for anyone who dislikes long journeys or has only a couple of days in the region, but for those with time it adds a very different chapter to a Mendoza itinerary.
