San Bernardino National Forest
There are over 500 miles of hiking trails in the San Bernardino National Forest. Trails vary in length from 0.25-mile nature trails to a 195-mile section of the Pacific Crest National Scenic Trail. Trails vary from easy to difficult with scenery from desert flowers to mountain pines.
The San Jacinto Ranger District offers one of the most unusual trailheads in the countrya tramway. From there you can either go for a short stroll or a more extended hike into the San Jacinto Wilderness. The Santa Rosa Wilderness, also in the San Jacinto district, has one official trail, the Cactus Spring Trail, which will immerse you in the Colorado desert environment.
The Big Bear District has a nice array of trails, from easy one-milers to the strenuous 3.6-mile Camp Creek National Recreation Trail or seven-mile challenge of the Siberia Creek Trail.
Cajon is the lowest elevation ranger district in the forest with some pleasant lower elevation trails and 30 miles of the Pacific Crest Trail, but the big draw here is the Cucamonga Wilderness.
