Part of the appeal of Potrero Chico is, put simply, the easy—and cheap—living. By day, climbers ascend spires like Crash Test Dummies, an exposed two-pitch 5.9 with an enviable view over the verdant valley at the top. Come evening, they buy fresh veggies and fruit at the local markets, then gather in campgrounds like La Posada to cool off in the pool, share stories, and drink margaritas in the shade.
