Silverwood Lake

Trek Highlights

From Cottonwood Station (south of Silverwood Lake), the trail begins with hedge-like bushes on each side. The route is rather rocky, crosses a creek, and climbs several switchbacks. The path gradually rises along a creekside until it reaches the level ridgeline of the summits. Follow the ridge to the southeast. A tiny spur trail climbs slightly up to Monument Peak. At the summit, there is a stone monument to the Mohave Indian Trail. From this peak, there are great views of San Bernardino.

Backtrack along the ridge for a mile and a half, and then leave the road. Climb a steep use trail to tag Bailey. From this summit, all you can see are trees. If you aren’t careful, it is easy to stray from the ridgeline.

After reconnecting with the ridge road, stroll in a northwest direction. Sugarpine is up a truck road with soft sliding dirt. During the hike, watch for off-road vehicles puttering about the dirt roads in this area.
