I just received a request for instructions on how to get to the Black Mountain Hiking trail head on my plugoo instant messaging.
From Interstate 280 in Santa Clara County, exit #16 El Monte/Moody Road and drive west on Moody Road. Go straight through the stoplight at Foothill College, and at a stop sign at about 0.6 mile, turn left to remain on Moody. Drive about 0.5 mile more on Moody, then turn left onto Rhus Ridge Road. Drive about 0.2 mile on this narrow road, then bear right into the parking lot.
This trailhead has parking for about 12 cars; no parking on Rhus Ridge Road. No entrance or parking fees. No toilet facilities or drinking water. No designated handicapped parking, and trails are poorly suited to wheelchairs. Maps available at information signboard.
The following is a link that describes the hike:
0.0: Begin at the gated entrance to Rhus Ridge Trail.
0.5: Path departs on the left. Continue straight on Rhus Ridge Trail.
0.9: Crest and junction. Turn right onto Black Mountain Trail.
1.6: Junction with path to Hidden Villa. Continue straight on Black Mountain Trail.
1.8: Second junction with path to Hidden Villa, on the right. Continue straight on Black Mountain Trail.
3.4: Near a high-tension power line, the narrow path widens to a fire road and begins a steep, relentless climb.
4.5: Junction. Turn right.
4.6: Junction. Turn left onto Monte Bello Road.
4.7: Hilltop. Turn right onto an unsigned path, and head a few feet to a rocky viewpoint.
4.7: Turn-around point.
9.4: Back at the trailhead.
Sorry I couldn’t respond directly, I was on another call.
