Hikes in San Bernardino County
San Bernardino County is the largest county by area in the contiguous United States, covering over 20,000 square miles. San Bernardino County stretching from the cities east of LA (like Ontario, Rancho Cucamonga, and San Bernardino) all the way to the borders of Arizona and Nevada. A good piece of the California desert lies within San Bernardino County, including Mojave National Preserve. These trail are not listed in the SoCal section of hikespeak.com and can be found with the other hikes in the California desert.
The San Bernardino Mountains are the grandest mountain range in the county, including the highest point in Southern California, the 11,500-foot summit of San Gorgonio Mountain. San Bernardino National Forest is the principal parkland preserving the San Bernardino Mountains, protecting over one thousand square miles in San Bernardino and Riverside counties.
A National Forest Adventure Pass is required to visit some trails beginning within San Bernardino National Forest. The pass can be purchased for $5 per day or $30 per year. The pass is valid at other national forests in Southern California as well, like San Gabriel Mountains National Monument and Angeles National Forest in the San Gabriel Mountains. Passes may be purchased from ranger stations within the park, at various local retailers, and online. Those without a pass may still enjoy several free entry points that are located outside the national forest boundary. An “America the Beautiful” National Parks and Federal Recreational Lands Pass can also be used in lieu of an Adventure Pass.
