A tour agency on Avenida España in the centre of Mendoza that runs the standard catalogue of day trips out of the city: half- and full-day rafting at Potrerillos, the high-mountain run up to Puente del Inca and the Aconcagua viewpoint, wine tours and adventure days.
This is the kind of operator you use when you want someone else to handle the driving on the Alta Montaña road, which is long, climbs to the Chilean border and closes without much warning in winter. Departures are daily in season.
