Discovery Park is located in Seattle's Magnolia neighborhood, and is the largest park in the city. Entry is free, and official hours are daily 4 a.m. to 11 p.m. The Discovery Park Loop Trail is a designated National Recreation Trail, 2.8 miles long with an elevation change of just 140 feet. It passes through both forest and open meadows, offers extensive views, good prospects for bird watchers, and can be hiked or jogged year-round.
Before there was a park here, this area was Fort Lawton and it is thanks to the fort that this large park is available to Seattlites who wish to explore an urban trail.
