      Japanese Gulch is owned by the people and city of Mukilteo. The trails here will soon be getting some improvements and expansion for both riders and hikers.

      NOTE The trails to the east of the railroad tracks are technically on BNSF and Boeing property and there are no trespassing signs which indicate this. While people have ridden this area for years and there haven't been reports of problems this could change at any time. Ride at your own risk.
