At 426 acres, the Dockton Forest and abutting Maury Island Natural Area make up one of the largest tracts of public land on Vashon Island. Here more than 10 miles of multi-use trails traverse attractive forests and towering coastal bluffs, and lead to a sprawling beach. The Maury Island Natural Area was owned by a gravel mining consortium which had plans for a controversial massive excavation. After a long battle spearheaded by local citizens and conservation groups, the mine was stopped. The former quarry lands along with the abutting Dockton Forest (transferred from DNR) were then transferred to King County Parks.

From the Dockton Park trailhead you can hike a series of trails and old woods roads through a forest of Douglas fir and madronas. The best hiking here however is via the old quarry access road. Take it for one mile winding down 300 feet into the quarry passing rusting conveyors and other old excavating machinery and reaching the old dock site and beach access.

A trail leading left from the old quarry access road is another great option. Follow this old road along the rim of the old quarry to excellent bluff top viewpoints. Enjoy sprawling views across Puget Sound to the Issaquah Alps and Mount Rainier.

When the tides are favorable, enjoy great coastal walking—usually all alone on the park’s one mile long cobbled beach. Walk along the base of steep forested slopes content that this coastline—the longest undeveloped stretch in King County didn’t become an open pit mine.
