Southeast of Walla Walla and Milton-Freewater, the Walla Walla OHV Trail is a 40 mile route through steep, rocky canyons along the north and south forks of the Walla Walla River.
To reach the trailhead, follow Walla Walla River Road from Milton-Freewater, at Forks Junction (about 5 miles) turn right and continue another 7 miles to Harris Park. A BLM Trailhead is about 1 mile past the park.
Note: As of September 2007, ATV riding on Forest Service roads is limited to designated routes. The designated Forest Service roads are all signed as open to ATV riding. Do not ride on unsigned roads. All paved road and double-lane gravel roads are closed to ATV riding.
