Fern Basin Campground offers basic facilities amidst a picturesque mountain setting in southern California. The campground has about two dozen campsites suitable for tent camping and small RVs or vans. Each campsite features a picnic table and a fire ring with grill. Vault toilets are provided, but there are currently no potable water facilities due to a water leak. Visitors are advised to bring their own water for drinking and cooking. Firewood is permitted only in designated fire rings, and fire restrictions may be in place during the season.
