With more than 2,400 acres of open space, William Frederick Hayden Park on Green Mountain is the second largest park in Lakewood. The park features a challenging network of multi-use trails. The summit, at 6,800 feet, offers unique and stunning views of the Denver metropolitan area to the east, as well as high mountain peaks to the west.
Since 1972, the majority of William Frederick Hayden Park was donated by, or purchased from, the Hayden Family. Once home to the buffalo, this park now provides rich habitat for a diverse array of wildlife, including coyotes, hawks, rattlesnakes, bluebirds, rabbit, mule deer and an occasional mountain lion.
