About
Overview
The Marion Mountain Campground offers a beautiful retreat in the San Bernardino National Forest. It provides access to a number of hiking trails that lead to some of the most spectacular views of Southern California.
The San Bernardino National Forest is submitting a proposal to increase fees at various sites across the Forest and is seeking public input. Please visit the https://www.fs.usda.gov/sbnf for more information and to submit comments regarding this proposal.
Recreation
Visitors enjoy sport climbing on rocks within the campground. Hiking on the nearby Marion Mountain Trail, which leads to San Jacinto Peak, is also available. Views from the peak extend to the ocean and across the Palm Desert, as well as the San Bernardino and San Gabriel mountains on a clear day.
The 11.8-mile Marion Mountain Trail is the shortest route up the mountain, but also quite strenuous in areas. Shorter hikes can be enjoyed on other nearby trails.
Facilities
Marion Mountain campground offers about two dozen campsites for both tent and small RV / van camping. All campsites are equipped with tables and campfire rings with grills. Vault toilets are available within the campground.
Please be aware that potable (safe for drinking) water may or may not be available at this campground. Please plan accordingly.

Nearby Attractions
The campground is located approximately 50 miles from San Bernardino, California, and seven miles north of Idyllwild, which is popular for its small-town atmosphere and variety of shops and restaurants.
