Frank Raines OHV Park is located not far from Patterson, CA. It is open to 4x4s from sunrise to sunset with a $5 admission fee per vehicle. The park is open to all OHV vehicles, so be sure to watch out for dirtbikes, quads, and SXS.
Fire Road is an easy trail that begins at the park's entrance. It is rated green by the park's rating system. The most difficult portion of the trail is a rutted hill descent. The hill can be descended in 2WD, but 4WD is necessary to make it back up. However, there is a parallel trail you can take to bypass the hill climb on your return. The winding trail connects to the park's other trails. There's also a small 4x4 "play area" with a few optional obstacles to test the capabilities of your vehicle. The trail dead ends into Ridgeline Trail, which is currently closed for fire repair.
Deer Creek Campground is located at the park's entrance. The campground has 34 sites with picnic tables, restrooms, and other amenities. Prices range from $15 to $30 per site.
