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.

Doughty Falls are fed by Cabbage Creek and only a small detour away from 'Deceiver Trail'. You will find a nice, little viewpoint from where you can watch the water fall down the mossy walls.

This viewpoint of Far Country Falls is just a very short detour from 'Indian Trail' on the western side of Cougar Mountain. It serves as a perfect spot for a nice photo in the woods.
