About Marion Mountain
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.

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.

FAQ
How do I get a reservation at Marion Mountain?
Campsite Sniper's current snapshot shows none of the 96 tracked site-nights open for online reservation at Marion Mountain. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Campsite Sniper has also detected 28 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Nov 2, 2026 18:20 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
How often do new openings appear at Marion Mountain?
Campsite Sniper detected 2 site-date openings at Marion Mountain in the last 7 days, 14 over 30 days and 28 over the last 90.
Which sites at Marion Mountain fit a 35-foot RV?
No RV-analyzable site here has a recorded maximum of 35 ft or more; the longest recorded is 20 ft. 15 of those 16 sites have a recorded maximum length and 1 does not; it is not counted as fitting.
Does Marion Mountain have online availability right now?
As of the Nov 2, 2026 snapshot, none of the 96 tracked site-nights are open for online reservation. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. A free Campsite Sniper alert tells you if any date opens online.
