"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,” writes At Cougar Mountain, you can “run through lush forest, fern-lined singletrack, over hills and along marshes, just minutes from the city,” they continue.


Cougar Mountain is one of the best-mapped trail systems in the Seattle suburbs. The great maps and trail signs make this 3,100-acre park very easy to navigate, which is convenient since this complex network is home to trail running routes of many different lengths. (Source)

The loop mapped here covers 7.6 miles of trail, but you could run for much longer if you prefer. In total, the park is home to 38 miles of hiking trails and 12 miles of equestrian trails. (Source)
