About Fern Basin Campground

The picturesque Fern Basin Campground is a perfect escape from a busy lifestyle. It provides peace and quiet in the mountains of southern California as well as access to countless recreational opportunities.


Visitors to the area enjoy hiking on the Marion Mountain Trail, which leads to San Jacinto Peak. 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 is also quite strenuous in areas.


The campground offers multiple single-family campsites for both tent and RV camping. Each site is equipped with tables and campfire rings with grills. Vault toilets are also provided.

Natural Features

The campground is located in a grove of mixed oaks and shrubs. A surrounding mixed conifer forest provides spotty shade for the campground. It is situated at an elevation of about 6,300 feet, in the mountains overlooking California's desert.

Nearby Attractions

The campground is located approximately 50 miles southeast of San Bernardino, California, and about seven miles north of the small town of Idyllwild, which is known for its shops and restaurants.

3 Reviews of Fern Basin Campground
Site 4 is not a tent site, the entire site is on a 70 degree angle.

Nothing on the campsite page or reservation page about this site. It's entirely slanted. Definitely a small RV site..

If you can get a site, do it!

I really love Idyllwild and Fern Basin is one of the few campgrounds there.  This is the definition of small mountain town so make sure to stop and check out the little coffee shops in "town".  The campground is fairly small and off a pretty rugged dirt road, but it's worth it.  I've stayed here a few times and it's always peaceful and quiet.  This is a tenter's campground if you ask me.  There's lots of hikes around the area - some steep, some like a dirt road.  There's an area off the far end of the campground that has big boulders that you can climb up on for a perfect view of the sunset.

Remote and Lovely

Nice campground outside of Idyllwild. Typical amenities however campground is unhosted so bring firewood from town. We scrounged and found plenty to burn. No stores that nearby for ice so come stocked.
