Culo De Gato (Cat’s Ass) is a cliff located about a half-hour’s drive from Potrero Chico and is home to a sizable cave and routes that are a bit steeper than most of the Potrero fair. Climbs tend toward the more difficult side of the grade spectrum.
There is however a handful of easier routes as well, and supposedly the multipitch “Crescent Moon Buttress” is quite good. There are also some futuristic looking projects that travel up the headwall above the center of the cave. All in all it’s worth a trip if you’re bored at the Potrero, especially if you need some shade in the winter.
