Cougar Mountain Trail Run routes

Just 15 minutes from Seattle, King County’s Cougar Mountain Regional Wildland Park, is a trail running paradise thanks to its rolling and runnable hills and trail variety ranging from narrow and technical to wide and groomed. Run through lush forest, fern-lined single-track, over hills and along marshes, just minutes from the city.
