Located in the "Issaquah Alps," Cougar/Squak Corridor Park is just minutes from Eastside cities such as Bellevue and Issaquah.
King County purchased 226 acres in the valley between Cougar and Squak mountains in 2014, with the help of The Trust for Public Land.
The new acreage has been added to existing public lands and creates a 730-acre Cougar/Squak Corridor Park that protects the headwaters of a salmon-bearing stream, and features deep forests, hiking trails and more.
The park is located at 10610 Renton Issaquah Rd. SE, Issaquah.
Trail length: Approximately 6.4 miles

Access: Cougar/Squak Corridor Park Trailhead. From I-90: Take Exit 15 and drive south on WA-900 toward Renton for 3.7 miles. Look for the entrance to the Cougar/Squak Corridor Park Trailhead on the left side of the road.
