About

Old Mill Campground is situated in a mature stand of mixed pine and fir within the Mendocino National Forest, approximately 10 miles west of Stonyford on Road M-5. This primitive campground offers approximately 10 campsites at an elevation of 3,700 feet and operates on a first-come, first-served basis with no fees required. The campground is particularly popular with off-highway vehicle enthusiasts due to its proximity to OHV trails and camping opportunities. The narrow access road makes it less suitable for large RVs or trailers. Facilities are basic, including vault toilets and picnic tables with fire rings, but no potable water is available, so visitors must bring their own. Quiet hours are enforced from 10:00 p.m. until 6:00 a.m. The campground is located in the Stonyford Recreation Area on the Grindstone District of Mendocino National Forest, offering a rustic camping experience surrounded by mixed conifer forest.

Directions

Located 10 miles west of Stonyford on Road M-5. The narrow access road is not recommended for large RVs or trailers.
