Getting There & Away
There are two bus departures per day for San Juan (AR$200, four hours), which pass through Calingasta (AR$35, 30 minutes). The stop is at the Servicompras.
The road between Barreal and Uspallata in Mendoza province takes you through some stunning scenery. A 38km stretch is unpaved, and likely will remain that way for some time. In a compact vehicle it is best handled cautiously; it's a dirt and rocky roadway with nothing, and likely no one around in case you need assistance.
