Explore Oregon's off-highway vehicle trails
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.
Know Before You Go
During fire season, restrictions may be in place on off-highway vehicle usage and trails on state forests and in areas protected by ODF. Always check the ODF fire restrictions & closures map before you head out. The following thresholds apply across all state forestland with developed OHV trails and on lands protected by ODF in northwest Oregon:
- At Low and Moderate Fire Danger, OHV use will not be restricted.
- At High, usage will be allowed before 1 p.m. and after 8 p.m.
- At Extreme, off-road vehicle use will be restricted.
