LL Stub Stewart State Park on Trailforks.com
Just 30 minutes west of Portland, the LL Stub Stewart State park is 1,800 acres comprised of more than 15 miles of trail, ranging from green to double black. These trails are generally open year round and have a little something for everyone!
UPDATE:
TRAIL CLOSURE UPDATE 2/20/2026: The Mountain Bike Trail area is partially open with some trails limited in access. Most MTB trails east of Caddywhomper Way in the core free ride area are open. Trails west of Caddywhomper Way in the core free ride area remain closed to the public due to ongoing forest thinning operations and trail construction. The Caddywhomper Way access trail from Hilltop Day Use area is open Monday-Friday after 5pm, and open all day on Saturday and Sunday. Closures are subject to change. For your own safety, please check posted signage and maps at the park when you arrive, and obey all closure signage that you come across while in the trail system.
Please respect the trail closure signs as there is heavy machinery operating in and around the closed areas. Visitors are advised to check park postings and signage or inquire with park staff before hiking or riding on the trail system for closure updates.
Access
Open 24 hours. A $5 parking permit is required. Alternatively, one can purchase a 12 month parking pass for all Oregon state parks.
History
Although planning for Stub began in the 1990’s, the park didn’t open until July 2007 with access for equestrians, hikers, disc golfers and campers. However, early in the planning phase of park, NWTA (then the Portland United Mountain Pedalers a.k.a. PUMP) was involved with a number of other volunteers to incorporate dedicated mountain biking opportunities. Park Rangers at the time helped develop recommendations for a “mountain biking only” area.
NWTA, together with Westside Trail Federation, facilitated the initial build out of mountain bike trails at Stub Stewart State Park. Moving into the future, NWTA is now collaborating with Oregon State Parks to manage, maintain, and scout additional MTB locations at Stub Stewart. Hundreds of folks have helped dig at volunteer work parties to make the Stub Stewart MTB trails a reality. Those trails finally opened in 2012, with a 5-mile cross country trail and one freeride trail. Over the last seven years, NWTA and WTF have added more than 10 miles to the mountain bike trail system and there’s still more to come!
