Construction Notice

Dockton Park and Dockton Forest are both undergoing construction, which affects different areas of the forest, park, and marina.

 

Dockton Forest - Mountain Bike Trails

Construction started in April 2021 on six new mountain bike trails. In the current phase, Vashon Mountain Bike Association (VMBA) will build three advanced lines with jumps and other features, a dual slalom trail, a beginner trail, and a pump track. Trail construction is expected to last into June. Dockton Forest visitors aren't likely to be impacted, as existing trails will be open during construction. VMBA will post signs on site to notify visitors of work sites and any potential construction impacts. To learn more about the partnership between King County Parks and VMBA, click here.

Park History:

In 1892-1910, the Dockton area was home to the west coast's largest shipbuilding dry dock. To commemorate the significance, an 18' bell tower with the actual historic bell that used to signal shift changes at the dock was installed at Dockton Park in 2007.
