Near Modesto and west of Patterson, the Frank Raines Off-Highway Vehicle Park has 126 acres open in the Deer Creek Canyon Area. The OHV park is tucked far enough into the hills that the terrain is very steep and treacherous. There is a year-round mud bog, and a rock-strewn creek to explore.
The trailhead is located 17 miles west of Patterson.
To reach the trailhead from US5, use the Patterson Exit and head west on Diable Grands Parkway to Del Puerto Canyon Road (about 0.75 miles). Turn right and proceed 17 miles up the canyon to the park.
Overall, Frank Raines OHV Park is the 49th most popular OHV & 4wd jeep trail of all 102 OHV routes in California.
