The Windy Boulders of Culp Valley is a popular high desert climbing area in Anza Borrego Desert State Parks.
Culp Valley features several dozen boulders, most of which are easily accessible from Route S22, the road down the mountain into the town of Borrego Springs. The granite rocks sits at a altitude of around 3000 feet in the San Ysidro Mountains, just to the west of Borrego Springs. Windy Boulders offers plenty of easy V0 routes, but also a nice range of more difficult problems.
Windy Boulders is aptly named for the strange nightly winds that blow even when other areas are windless. You can pull off on the dirt areas on the side of S22 and hike a few minutes to the rock of your pick.
As with the rest of Anza Borrego, this area gets extremely hot in summer, and even in the fall and spring the mid-day sun can be brutal. Bring lots of water if your going to climb or hike here, and keep an eye out for rattle snakes.
Culp Valley Primitive Campground offers rugged camping – vaulted toilets and a place to pitch a tent – within a short hike of most of the boulders. The campground fills up quickly during wildflower season, so plan accordingly. If you can’t find camping here, there’s plenty of non-campground places to crash in Anza Borrego Desert State Park, or you could check out the hotels in Borrego Springs.
