Slide Mountain

If you enjoy a great hike that ends with a great 360 degree view of the North West section of the Angeles National Forest, including Pyramid lake, then Slide Mountain Lookout is the place to be.

The Slide Mountain Lookout is a two-story metal tower with the cab on top. Built in association with the construction of Pyramid Reservoir in 1969, it has vistas of Interstate 5 and the Sespe Wilderness.

Slide Mountain is listed in the National Historic Lookout Register.
