In October, I went to Horse Flats two weekends in a row. This small area is located in the Angeles National Forest, in the San Gabriel Mountains. From the west side of Los Angeles, it takes anywhere from 1.5 to 2.5 hours depending on traffic. The granite bouldering is a great getaway from the city. Almost every time I’ve been there, we were the only people there. You’re more likely to see mountain bikers hopping down the path than other boulderers. Due to the high elevation, this is a summer and fall destination. For a laugh (and a thrill!) try the classic barndoor arete.
