The Big Tree 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 trail connects with good trails inside and out of Cougar Mountain Regional Park. Trails head out of the park to the south and east, and allow hikers to loops back to the trailhead.

For example, head down the Big Tree Ridge trail to the Red Cedars trail. From there, take 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 in the trailhead before heading 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 before you go and bring one with you in order to keep your bearings.

Getting There

From I-90: Take exit 13 onto Newport Way, heading southeast toward Issaquah for a few miles. Just after passing Oakcrest Boulevard on your right, with a large SUMMERHILL neighborhood sign, a white metal gate on the right marks the trailhead. There is a trailhead sign beyond the gate with a map and a wooden sign pointing to the Big Tree Ridge Trail and Military Ridge Trail.
