About the Park
Cougar, Squak and Tiger Mountains, also known as “the Issaquah Alps,” rise above Lake Sammamish and together provide more than 15,000 acres of connected public forest lands. There are more than 100 miles of connected trails and the dense forests and wilderness are home to numerous birds and wildlife.
Cougar/Squak Corridor Park is a 730-acre valley between Cougar Mountain Regional Wildland Parkand Squak Mountain State Park, creating contiguous 5,000 acres of public land. This forested park protects the headwaters of a salmon-bearing stream.
There are about three miles of gravel roads winding through an area of the park that used to be a car-camping campground. The 2.5 mile Margaret's Way trail, beginning at the Squak Mountain Lodge, is named for Margaret Macleod, a trails and open space advocate who was responsible for the preservation of hundreds of acres of open space in the Issaquah Alps, including the Cougar-Squak Mountain Corridor. Near the top of the park, Margaret's Way connects to Chybinski Loop Trail, Debbie's View Trail, and many other trails connecting to Squak Mountain State Park.
