About this place

Added by Jennifer Broome

William F. Hayden Park on Green Mountain has a challenging network of multi-use trails and because it is so close to town, makes for a great weekday escape.

Green Mountain Trail is a 6.5-mile loop and has a challenging ascent to the park's highest point. Because the mountain is one of the first to rise out of the plains, you get unique views of where the mountains meet the prairie and fascinating geology. The summit, at 6,857' offers stunning views of Denver and the plains to the east and impressive mountain peaks to the west. Because it is only about 20 minutes from Denver, it could be considered an urban mountain. Once home to buffalo, the park now has a diverse wildlife population including coyotes, hawks, rattlesnakes, bluebirds, rabbits, mule deer, and occasionally a mountain lion. The north side of Hayden Park was used as an artillery target range for the Colorado National Guard's Camp George West during the first half of the 20th century. Stay on marked trails as old military munitions and debris can still be found in the park. Green Mountain trail is rated moderately strenuous. Because of the lack of trees, this is a sunny hike, which is great in winter. Don't forget your sunscreen!

Perfect Sunday walk
Beautiful walk! We did it November 20th and the first half a mile was a bit muddy. But after that it was fine.
