About the Park:
The 3,000+ acre Cougar Mountain Regional Wildland Park is connected to Squak Mountain State Parkby Cougar-Squak Corridor Park, which together is about 5,000 acres of protected area in the public land known as the "Issaquah Alps." The park is between 1,000 and 1,600 feet above sea level.
Cougar Mountain Park has over 35 miles of trails wending through diverse habitats such as mature second growth forests, streams and wetlands, and cliffs, and nearby caves. While there are sweeping views of Lake Sammamish, the Cascades, and Bellevue, Seattle and beyond, there are areas of the park that are more remote from the sights and sounds of nearby urban development.
Although most of the trails at Cougar Mountain Regional Wildland Park are primarily for hikers, some trails allow horse-riding. Due to hazards from historical mining activities in the park, you must stay on the trails.
Park Activities: dog walking, hiking, horse riding, nature observation, parking lot, picnic area, volunteer. No mountain bikes.
