"This short but scenic semi-loop trip, via Rocky Ridge Road and the Cuesta and Upper trails, takes you atop 2000-foot Rocky Ridge, the border between Las Trampas Wilderness and EBMUD lands of the Upper San Leandro Reservoir watershed. Rocky Ridge, a Nike missile site during the Cold War, rises midway between Redwood and Anthony Chabot regional parks and Mt. iablo State Park, making it a commanding vantage point with great views. After passing through the cattle gate, you begin a steep uphill walk on paved Rocky Ridge Road. After a short while the grade eases somewhat, but more climbing is just ahead, past stands of coast live oak and California bay. In wet weather, water may be running here in channels on both sides of the road. If you are here late in the day, listen for the “hoo, hoo, hoo-hoo” of a great-horned owl, but don’t be fooled by a mourning dove’s plaintive cooing. After climbing for about 0.5-mile, you round a bend and reach a junction with a single-track trail heading left and steeply uphill. Turn left, and immediately come to a fork with a trail post in the middle. Here the Rocky Ridge Trail heads right and the Cuesta Trail, your route, goes left."
