William F. Hayden Park on Green Mountain

View of wildflowers and mountains at William F. Hayden Park at Green Mountain.

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 6,800 ft. summit of Green Mountain Trail offers unique and stunning views of the Denver metropolitan area to the east and 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.

Trail Use Guidelines

Please help protect park resources by remaining on designated trails only. Avoid using wet or muddy trails; the trails tend to dry earlier than many of the foothills parks, making the park a fantastic winter destination.

Proper yielding guidelines:

  • Cyclists yield to ALL other trail users. Slow to a safe speed to pass. Make calm and friendly verbal contact prior to passing. Dismount for equestrians.
  • Pedestrians should avoid blocking the trail. Yield to equestrians.
  • All users must keep dogs on a leash at all times. Be courteous, communicate and listen. The trails are for everyone!
