Catavina boulder and cave-painting walk

The walk begins at a signed pull-out on Highway 1 at kilometre 174 in Catavina, where free parking is available and a local guide often waits at the trailhead to lead visitors in for a fee of around MXN 100 per group; the guide is not strictly required but helps in locating the paintings and interpreting them. The round trip covers just 1.5 km with about 40 m of elevation change, following a sandy path that winds between granite boulders into the heart of the Catavina boulder field, with a short scramble over rock in the final stretch to reach the shelter. There is little shade beyond the boulders themselves, though the short distance keeps sun exposure manageable outside the hottest hours. Landmarks along the way include dense stands of boojum trees, cardon cactus and elephant trees found almost nowhere else on earth, and the rock shelter itself, a shallow overhang painted with red and black Cochimi figures that marks the end of the walk and the natural turn-around point. No water is needed for a walk of this length, though carrying a small bottle is sensible in the desert heat. There are no huts or facilities beyond the highway pull-out, and no other services are available in the immediate area besides a few small restaurants back on the highway in Catavina itself.
