Here's a photo of the granite south wall of Cerro San Gabriel, just north of a small village of the same name, in the Cajon del Maipo. About 90 minutes from northern Santiago, and about a one hour approach hike over talus. 400m, and about 10 pitches of fine granite. Routes from 5.7 to 5.12. No guidebook, no topos, but you can find a few bolts and/or slings at belay stations.

We climbed here a few weeks ago, had a few route-finding issues, but the rock and route were spectacular when we found our way.
