Bridle Trails State Park, a 482-acre day-use park, is well-known for its horse trails and equestrian shows. The forested park is on the northeast edge of the Seattle metropolitan area. The park has been under state ownership since the 1880s. By the 1930s, the area was popular as a place for horseback riding, and a trail system had been developed by community riding enthusiasts. Concerned about protecting the land, citizens petitioned the state legislature to make Bridle Trails a state park.
