Sunnyvale Mountain is a climbing area in Sanborn County Park, on county land in California. It sits among a cluster of bouldering spots, with Tree-In-The-Wall Boulder and Drunk as a Skunk Boulder each about 0.2 miles away and Biddles about 0.3 miles off. Late spring and early fall are the most comfortable times to visit. Typical averages from a nearby weather station show May highs around 67°F and October highs around 71°F, with only a handful of wet days in each month. That station sits about 500 feet lower than the park, so temperatures on the mountain run a little cooler. The Skyline Trail and John Nicholas Trail are both within half a mile, and the Peterson Trail is about 0.7 miles away. For paddling, the San Lorenzo River is roughly 9 miles off.
