When navigating to the peak, some of the downed trees and vegetation can make it a bit confusing. There's white spray painted arrows on the ground at the most confusing spots, so keep an eye out for those!

Cougar Mountain Park spans nearly 3,000 acres, featuring over thirty-five miles of fantastic trails winding through second-growth forests, streams, wetlands, cliffs, and historical mining caves. There are breathtaking views throughout the park of the Cascade Mountains, Lake Sammamish, Bellevue and Seattle, along with other more secluded areas, which are ideal for spending time surrounded by nature away from the fast pace of the city. Most trails are mainly for hikers; however, some allow horseback riding, so keep an eye out for equestrians as you explore this beautiful area.

Hiking among towering moss-covered rocks with small caves to either side is a bit creepy, but it's worth the visit! It's not very well marked, but you have stairs to one side if you don't want to walk in between the rocks. There's a wooden fence blocking off an unsafe path between rocks, so if you see that, you're in the right place.

This is the quieter of the peaks in the area due to the fact that it was donated with a stipulation that the land remained in its natural state. You can feel the peace and tranquility from this point.
