Southern California's highest and most rugged mountains are in the San Bernardino and San Jacinto ranges, in a unique region where desert cactus and pine trees, plus snow-capped peaks and palm oases, are found in close proximity. With the Pacific Crest Trail weaving its way through the mountains and desert, there are endless opportunities to explore Southern California trails. After more than 40 years in print, San Bernardino Mountain Trails remains the bible for Southern California hikers. This updated guide by veteran hiker and author David Money Harris contains new trips as well as old favorites -- 100 hikes that traverse San Bernardino National Forest, the Santa Rosa Mountains, and the San Jacinto Mountains. This edition brings John Robinson's classic guide up to date with the latest trail conditions. Eight old trails, especially in areas that have become overgrown after fire damage, have been replaced with recently built or more heavily used trails. San Bernardino Mountain Trails is noted for its comprehensive coverage of the San Bernardino, San Jacinto, and Santa Rosa Mountains and its meticulously researched history of the ranges.
