Hilltop Boulders is a bouldering area in Anza-Borrego Desert State Park in California, managed by State Park and Recreation. It sits among a cluster of climbing areas, with Marvel at the View and Wakanda each about 0.2 miles away and Windy Boulders North about 0.3 miles off. The Culp Valley Trail starts about 0.4 miles away for anyone who wants to pair a climb with a walk. The boulders here are all boulder problems, and the routes run from V0 to V7 on the V scale. The Mexican Hat is a V3, and Steel Toe is the hardest at V7. The YDS grades for the area's single route, Can't Beat The View, sit at 5.6. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Julian show May highs around 69°F and October highs around 71°F, while July and August average about 86°F. That station sits roughly 1,000 feet lower than the boulders, so temperatures on the rock run cooler.
