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.

Is MARION MOUNTAIN fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches MARION MOUNTAIN in Idyllwild, CA for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification — and on Recreation.gov we can put the site straight into your cart, so it is held while you get to your phone.
