Why almost everyone starts in San Rafael
The canyon begins about 40 km south of San Rafael along provincial road RP173, and San Rafael is where the agencies, rental cars, fuel and the tourist information office are. Whichever option you choose, you will start and finish your day here.
- Distance from San Rafael to the first viewpoint (Valle Grande): roughly 40 km.
- From Mendoza city, add about 240 km of highway before you even reach San Rafael.
- There is no scheduled bus service that drops you at the canyon viewpoints.
Option 1 — Group day tour or half-day tour
The default choice for visitors without a car. A local agency provides the vehicle, a driver-guide and stops at the main viewpoints. Some itineraries can add rafting on the Atuel or a boat ride on one of the reservoirs.
- Typically covers Valle Grande, the canyon viewpoints and El Laberinto, sometimes El Nihuil.
- Half-day tours focus on the viewpoints; full-day tours add a water activity or a longer route.
- Book ahead in peak season and on public holidays — seats do sell out.
Option 2 — Private transfer with driver
Best if you are travelling as a family, a small group, or with camera gear. You choose the stops and how long you spend at each, which matters a lot if you want sunrise or sunset light on the rock walls.
- Priced per vehicle rather than per person — better value for groups of three or more.
- Lets you reach the Volcán Overo turn-off or stay late at a viewpoint.
- Ask in advance whether the driver waits at each stop or drops and returns.
Option 3 — Self-drive or rental car
The most freedom and usually the cheapest for two or more people. You control the pace entirely, which is why photographers and anyone wanting a sunrise start prefer it.
- Fill the tank in San Rafael — there is essentially no fuel along the canyon.
- Download offline maps: mobile signal is unreliable inside the canyon.
- RP173 has tight curves and cliff-edge sections; avoid driving it at night.
What to check before you book
- Whether the price includes entry fees, lunch and water activities, or only transport.
- The exact meeting point and departure time — some tours leave very early.
- The cancellation policy for weather, since strong wind can close boat and water activities.
- Whether the vehicle is suitable for the dirt detours if you want the Volcán Overo route.
Frequently asked questions
A half-day tour usually runs about four to five hours and covers the main viewpoints. A full-day tour with a water activity or a longer route through to El Nihuil typically takes seven to nine hours including transfers.
Yes. Self-driving along RP173 is entirely normal and gives you the most freedom. There is no public bus to the viewpoints, so without a car you will need either a guided tour or a private transfer.
In peak season and on public holidays, yes — confirm at least a day ahead. Outside those periods you can often arrange a tour on short notice, but rafting and boat activities depend on water levels and daily demand.
The standard viewpoint tours involve little walking and suit most ages. Rafting has age and fitness requirements set by each operator, and the rock labyrinth walk involves loose ground with almost no shade.
