Tillamook State Forest OHV
Tillamook State Forest OHV Area in Washington County, Oregon, is managed by the Oregon Department of Forestry and concentrates its approximately 52 miles of designated OHV trails around the Browns Camp staging area off NW Browns Camp Road near Forest Grove, approximately 30 miles west of Portland in the Oregon Coast Range. The Coast Range location gives Tillamook OHV riding a character specific to the wet western Oregon mountains: heavily forested corridor with Douglas fir, western hemlock, red alder, and sword fern understory; steep terrain where the ridges drop sharply into the creek drainages flowing west toward the Tillamook Bay watershed; and the consistently wet trail conditions that define Coast Range riding, where clay-soil sections become impassable after significant rain and the trail system requires active management to stay rideable. ATVs, UTVs, and dirt bikes are permitted on designated trails, most trail corridors are too narrow and steep for full-size 4x4 trucks. The trail system was substantially damaged in the 2020 Beachie Creek fire and has undergone a phased reopening from 2021 through 2023 with extensive restoration work; current trail status should be confirmed with the ODF Forest Grove office before visiting (503-359-7402). An Oregon OHV registration sticker and a Discover Oregon pass are both required for all riders. The Browns Camp trailhead has restrooms and trailer loading ramps. Hours are dawn to dusk year-round on open trails.
