  • Drive north on Angeles Crest Highway (SR 2) for 9.5 miles to its junction with Angeles Forest Highway (N3). Turn left.
  • Drive north on Angeles Forest Highway 14.2 miles to Mill Creek Summit. Turn left on Mount Gleason Road (3N17). Note your odometer and go as follows:
  • At 6.2 miles, a fork, where the paved road goes into a Los Angeles County correctional facility. Take the left fork (dirt) around the detention center.
  • At 8.8 miles, a gated paved road goes right (north) just past a microwave tower. Park at the gate or nearby (don't block the gate).


  • From the parking area (6428'), pass the gate and hike up the road to the summit, a large open area. There is usually no register on this summit.
  • To find the HPS register, travel north past the summit area about 0.3 miles on a dirt road to the summit of bump 6502. This is slightly south of and above where the PCT intersects the dirt road. The register is in a rocky patch just east of the road.


The Pacific Crest Trail (PCT) crosses the north ridge of Mount Gleason. From this point it is possible to hike up the ridge less than 1/2 mile to the summit area. This makes it possible to hike Mount Gleason via the PCT from any convenient trailhead along the PCT depending on how long you want the hike to be.


[by G. Wysup] The Nike fire control radar system was located on the summit. The admin and launch facilities were at LA Co. correctional facility.
