Dockton Forest Mountain Bike Trails


The Dockton Forest MTB Trails consist of 2.5 miles of stacked-loop singletrack with connection to the beach and King County's Dockton Park by way of the Huckleberry trail. These trails drain pretty well and offer great spring riding since they roll better with a little moisture. The weather is temperate and trails are open all year.

While equestrians usage on Vashon is prevalent, horses rarely ride in this section of the park; if venturing out on the Huckleberry Trail be aware of equestrian use and be sure to communicate clearly and be prepared to dismount your bike. 


The green (beginner) loop offers easy riding for beginners or anyone needing a warm up. This loop consists of:

  • Gravel Grinder
  • Erratic
  • UFO

The blue (intermediate) loop is larger, and offers more advanced riders a chance to corner and get some air on various berms and jumps.  Features are progression-friendly and can mostly be rolled for those not yet comfortable with wheels-off-the-ground. Intermediate trails on this loop are:

  • Feeder Line
  • Chairlift
  • Bumpy Monkey
  • Flying Monkey
  • Dr. Jekyll
  • Mr. Hyde

The Maury 40, or Dockton Forest Lease, was transferred by the Common School Trust to the King County Parks Department on a 25-year stewardship lease in 2005. The land is designated as open space for passive recreation. No known proposals for trail development exist.

Advocacy groups on the island have a vested interest in the area because of its critical role in the local watershed. These groups include the Vashon / Maury Land Trust and the Dockton Water Association.
