Green Lake is one of Seattle's most beloved parks. Its expanse of water and green space in the center of a dense urban neighborhood draws thousands of people daily from all over the city. The park serves as a natural preserve for hundreds of species of trees and plants, as well as numerous birds and waterfowl. The 2.8-mile path around the lake provides a perfect recreational spot for runners, bikers, skaters and walkers. Many others use the athletic fields or visit the park for boating, picnics and swimming.
