Hiking Big Tree Ridge

The Big Tree Ridge Trail is an accessible, high-quality trail with moderate grades — excellent for new hikers.

Enjoy views of the snowy Cascades year-round when it is clear. In winter, Squak & Tiger Mountains loom out of mists and low-hanging clouds; giving the hike a mystical atmosphere. The Big Tree Ridge Trail starts at a parking lot that was built in 2023 on Newport Way NW. It is at the northeast corner of Cougar Mountain Regional Wildland Park.

The trail climbs towards southwest at a steady grade with several switchbacks for 0.9 miles, gaining roughly 700 feet. It ends at a junction with Red Cedars trail and Military Ridge trail, which connects to Harvey Manning Park at Talus. You can head back the way you came to the trailhead here.

But the trail connects with many trails inside and out of Cougar Mountain Regional Wildland Park. You can explore the northeast part of the park connecting various trails.

For example, climb up the Big Tree Ridge Trail and turn right to Red Cedars trail. From there, hike up the Surprise Creek trail to the Shangri La trail which will take you to the Harvey Manning Trailhead. Check out the "Million Dollar View" promised by the sign at the trailhead. This route is about 2.2 miles with 1,350 ft elevation gain. After enjoying the Million Dollar View you can head back the way you came to the Big Tree Ridge Trailhead.

WTA has done lots of work on Cougar Mountain since 2009, but signage may not be entirely up-to-date. Take a look at a map and plan your route before you go and use a GPS tracking app on your smartphone in order to keep your bearings.
