Black Mountain via Black Mountain Trail

From the small - and often packed - parking lot off Rhus Ridge Road, take the dirt road into the forest, past the caretaker's house and through a gate. You'll get your first view, overlooking Los Altos Hills, after about a half mile. At about a mile, you reach a four-way intersection. Turn right onto the Black Mountain Trail. Stay on the Black Mountain Trail, passing the Hostel and Ewing Hill trails on your right. At 3.5 miles, the Black Mountain Trail switches from singletrack to dirt road and becomes quite steep. Pass the narrow Quarry Trail on your left, and keep climbing toward the antenna garden near the summit. Pass the antennas, and continue toward Monte Bello Road, when you'll turn left to reach the rock formations at the summit.Return the way you came.
