Dockton Playground Temporarily Reopen

The Dockton Park playground is currently open. The reopening of the site is temporary due to more work that needs to be completed by the surfacing installers. Once the warranty work for the surfacing is scheduled, the playground will need to be closed temporarily again to finish work. That work is estimated to take two to three weeks. The playground has been inspected and is safe for use, though the swings will still not be available until the resurfacing is completed.

Thank you for your patience and understanding as we complete this important work!

About the Park

Located on beautiful Vashon/Maury Island and a short ferry ride away from Seattle and Tacoma, Dockton Park provides a public boat launch, moorage, a playground, beach access, and picnic facilities on Quartermaster Harbor.

Across the street from the park is access to Dockton Forest, 86 acres of working forest land that is connected to Dockton Natural Area and Maury Island Natural Area, creating a network of 12 miles of soft-surface multi-use trails - including 3 miles of beginner, intermediate, and advanced mountain bike park trails.

Marina and Playground Improvements

Dockton Marina is open with moorage for up to 30 boats.

A multi-year project consisting of two phases is underway to improve the Dockton Marina. Completed in May 2022, Phase 1 replaced various piles and finger piers internally on the dock. Other improvements include new swim dock, fire suppression system, sewage pump out station, hardware replacements, nonskid coating, fixed pier cross bracing replacement (under bathroom). The new dock is constructed with plastic grating that lets light through and creates better habitat for sea life. 

Phase 2 is in final design and will include removal and replacement of deep-water creosote piles, replacement of breakwater section of floating dock, and replacement of the boat ramp dock. Construction is estimated for 2024. 

The new Dockton playground is now open! Keeping with the maritime nature of the park, the new playground is a ship-themed play structure with improved ADA accessibility, two slides, swings, a net climber, musical instruments, spinning rope climber, and more. Learn more about the new playground on the King County Parks blog.

Park History

From 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. A walking trail with interpretive signs details the area's history starts at Dockton Park and continues up into the neighborhood.
