The south end of the Grindstone Ranger District offers over 200 miles of some of the most enjoyable and challenging OHV routes in the nation. The "Mendocino OHV Corridor" is a designated 40 mile, east-west route across the south end of the Forest connecting the Stonyford OHV Staging Area and the Upper Lake OHV Staging Area.
The riding area varies in elevation from 1,700 feet (at Fout Springs), to almost 6,000 feet (near Goat Mountain). Vegetation varies from low elevation chaparral to tall pine and fir forest in the high country.
The Grindstone Ranger District is not an OHV "park". Off-highway vehicle recreation is just one of the many uses allowed on National Forest lands. Please be considerate of others you may encounter in the forest.
