State forests offer some of the best Off-Highway Vehicle (OHV) trails in the Pacific Northwest. In the Tillamook State Forest, 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 of the Tillamook State Forest area are mostly single track trails for motorcycle use only. Side-by-side enthusiasts will enjoy the four-wheel drive trails in the Tillamook State Forest and the bulk of the trail network in the Nicolai Mountain OHV Area.

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: 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. In the Tillamook State Forest, side-by-side ATVs are only allowed to operate on the 4-wheel drive trails and the gravel roads in the designated OHV areas.

For more specific information about OHV use and the fire season status of the OHV trails on the Tillamook State Forest, visit the Tillamook State Forest blog.
