  • Drive east on I-10 to I-15, then north on I-15 to SR 138. Turn right (east).
  • Go 8.0 miles to the junction with SR 173 on the left near Lake Silverwood. Keep straight on SR 138.
  • Drive another 2.6 miles and exit on Cleghorn Road (2N49). This is also the main entrance to Lake Silverwood. At the bottom of the off-ramp, turn right on 2N49. Note your odometer and go as follows:
  • At 0.8 mile, pavement ends.
  • At 2.4 miles, fork. Go right.
  • At 4.0 miles, Cleghorn Pass and a hairpin turn at two water tanks.
  • At 6.3 miles, Cajon Lookout road fork on the right. Park here. (The gate is sometimes open, but there is no way to confirm this in advance.) Adequate parking.


  • From the parking area (5000'), hike west down the road past the saddle at 4645' and continue about 1/2 mile before reaching a shallow saddle 1/4 mile east of the former lookout (west of the peak).
  • Go up the use trail that starts here and leads east though the brush to the summit. The "lookout" has been removed and the remaining radio facility location is not the summit. The brush can be very dense if not groomed.


The dirt roads are seasonal.
