It's a drive along a rough road off Hwy 200–Altavista, then a 1.5km walk up to this site; get good directions first, as it's not signposted. The site is well stocked with petroglyphs, some geometrical, some depicting human figures. A path leads you past many carvings, with Spanish and English signs explaining them.
The visit ends in a glade with cascading water and rock pools for a dip. The site is somewhat difficult to find, but you can always hook up a tour with Xplore Chacala.
