SaveThis trail network was called the "K2 trails" (because the K2 employees built most of them and whatever stunts have survived). The trails start at Dockton park, on Maury Island (Vashon and Maury connect at a narrow spit, "the portage", at the north end of Quartermaster Harbor. These trails have some grinding climbs and bombing DH runs. There is twisty tapewormish stuff in the gloomy 2nd growth woods, and some rolling singletrack through glades, a la Beaver lake.
From the North Ferry Dock (Vashon Heights):
Approximate distance: 14 miles.
Proceed south on Vashon Hwy SW past the town of Vashon.
The highway will jog to the right (west) and descend a hill
Turn left (east) on SW Quartermaster Drive.
Follow Quartermaster Dr. along the water until it stops at Dockton Rd. SW.
Stay on Dockton Rd. SW, shorly after the speed limit becomes 25 MPH, look for the parking areas and the boat ramp on the right side.
From the South Ferry Dock (Tahlequah):
Approximate distance: 14 miles.
Proceed North on Vashon Hwy SW past the town of Burton.
The highway will cross a concrete bridge;
Turn right (east) on SW Quartermaster Drive.
Follow Quartermaster Dr. along the water until it stops at Dockton Rd. SW.
Stay on Dockton Rd. SW, shorly after the speed limit becomes 25 MPH, look for the parking areas and the boat ramp on the right.
From the parking areas, the trails are all uphill. You will find a trail climbing out of the gravel parking area, you can ride east (and up) SW 260th St, and there is a trail on the east side of Dockton Rd SW, north of SW 260th st. Additionally, you will find multiple trails north and south as you ascend SW 260th St. I urge you to explore the variety of trails on both sides of SW 260th St. If you get lost, generally head downhill.
