From Vecindario, take GC-65 to San Bartolome. After roughly 18 km, turn left into GC-651 towards La Sorrueda and La Fortaleza. After another km turn right (GC-652), leading through the northwestern part of the village. Follow the road, which soon turns into a dirt road. Leave your car at a place without compromising anyone and continue the rough track by foot (or your 4WD) to the base of the canyon, roughly at the inlet of the reservoir (when full). Follow the riverbed 300 m upstream; the walls will appear to your left.
