Lightning Ridge and vicinity

The one-mile interpretive loop trail at Lightning Ridge is short, but rich in flora. The trail was created years ago by the Forest Service, and printed copies of the interpretive flier are still found in the green metal box at the start of the trail. This easy trail is located at Blue Ridge Summit, which is the point where Angeles Crest Highway crosses Blue Ridge, at an elevation of 7,360 feet.

The Lightning Ridge trail passes through a delightful black oak woodland, and ends higher up on Lightning Ridge, where it joins the Pacific Crest Trail. Near that junction, there is a magnificent southward view along the length of the valley of the East Fork of the San Gabriel River. On the other side of the highway from Lightning Ridge is Inspiration Point, a spectacular overlook of this same valley.

Nearby, a gravel road heads east along Blue Ridge. Part of this gallery page includes photos from the Blue Ridge road.
