Parking Lot Closure at Big Tree Ridge

Please be aware: the parking lot at Big Tree Ridge Trailhead will be closed until improvements to the trailhead can be completed. New construction will not take place until the Summer of 2021 and the parking lot will be closed from now until the construction is through.

King County is requesting that hikers additionally do not park in neighboring streets or residential areas. The map below shows trailheads on Cougar Mountain with available parking at this time, and with 3,100 acres of land available to explore on Cougar Mountain, there is plenty to see at those trailheads as well.

Big Tree Ridge is a small trailhead located near the sensitive habitat of Tibbets Creek, and therefore historically has not has enough space for a designated parking area. Construction will make improvements to this trailhead in light of its challenging location.

Luckily, there are many other trails on both Cougar Mountain and in the Cougar-Squak Corridor to explore. Download a map of the area to start exploring, or visit Washington Trails Association’s website to see trip reports from nearby trails.

Thank you for your cooperation during this time. Please visit King County’s website for updates and information.
