State forests offers some of the best Off-Highway Vehicle (OHV) trails in the Pacific Northwest. The Browns Camp, Jordan Creek, and Diamond Mill OHV areas alone provide more than 250 miles of riding opportunity through some of the more scenic areas of the forest.

OHV areas include trails for motorcycle, quad, and four-wheel drive enthusiasts that range from easy to challenging. The trails in the Diamond Mill area are mostly single track trails for motorcycle use only.

In addition to trails, the Browns Camp, Jordan Creek and Diamond Mill campgrounds and staging areas provide overnight and day use opportunities. Day use is free unless you are occupying a campsite. *Please note that side-by-side ATVs such as the Yamaha Rhino, the Kawasaki Mule, and the Polaris Ranger series are considered Class IV ATVs and are only allowed to operate on the trails designated and signed for their use.
