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.

After a long drought, nothing is left of the waterfall... but still a nice and quiet place to sit and relax.
