Rating: ★★★★☆(4/5) - Worth a Trip
Located near the intersection of Interstate 70 and Colorado Highway 470 in Lakewood, William F. Hayden park, also known as Green Mountain Park, features some of the best views of the Denver skyline. Climb to the top of the mountain on the Green Mountain Trail Loop, or shorten your hike by taking the John O. Hayden Trail on the way down.
