Trek Highlights

Cleghorn Road is an off-highway vehicle (OHV) route to Cleghorn Mountain. The road has hard-packed sand with lots of tread marks. After the first snow storm of the season, there is fresh pow on the slopes. Park at the staging area to shave one mile round-trip.

Take a sharp left turn on 2N47. The path rises gently. Without all the snow and ice, this hike would be a breeze. From the summit, there are amazing views of the tallest peaks of the San Gabriels and the Antelope Valley.
