  • Go north on I-5 to the town of Gorman. Get off on the signed Gorman exit.
  • Turn left at the bottom of the off-ramp and go under the freeway.
  • Go 0.1 mile to Peace Valley Road. Turn right.
  • Go 1 mile to the entrance to Hungry Valley Recreation Area on your left (paved). Turn left. Note your odometer and go as follows:
  • At 0.2 miles, entrance station. If manned, you can avoid payment of the fee by telling the State Park employee that you are passing through to Alamo Mountain.
  • At 5.2 miles, intersection. Turn right (west) toward "Piru Creek", signed.
  • At 11.4 miles, Piru Creek crossing. There is a seasonal gate just before this stream crossing.
  • At 13.4 miles, the pavement ends.
  • At 17.8 miles, fork to the left. Keep right.
  • At 17.9 miles, junction with the Alamo Mountain Road. Go straight. Note your odometer again and go as follows:
  • At 3.3 miles, fork immediately beyond a small road cut through the ridge. Turn right.
  • At 4.5 miles, the road reaches its highest point at a shallow ridge south of the peak. Park here.


  • From the parking area at the shallow ridge (7020'), hike north along the crest of a gentle ridge, keeping the western drop off visible to your left to simplify navigation in this easy terrain.
  • After passing over a couple of small bumps the steeper summit area becomes visible. The register is found on a small rocky outcrop north of the more dramatic rock structures, and is the easternmost of the two highest summit bumps.
