Confirmed from William Frederick Hayden Park's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
Scenic mountain park & wildlife habitat with a multi-use trail system, plus restrooms.
What runners say about William Frederick Hayden Park
“There are numerous ways to enter the area and everything is very well kept and maintained.”
“Beautiful views throughout and is a great work out with the steep uphill and downhill climbs.”
“It's great because there are many trails and it can be peaceful or challenging, depending on the trail you pick.”
“There are nice views throughout the park and you can summit Green Mountain which is a very easy hike.”
A beautiful, sunny 62° December day in Lakewood. No trees in the trail which is great for getting sun on a cold day but could get today in the summer. There are nice views throughout the park and you can summit Green Mountain which is a very easy hike.
I love this park. From the parking lot to the telephone 🗼 takes about 35-40 minutes. The top is windy. There is some ❄️ and a lot of mud. From the tower to the top takes about 20 min or so. If you take the right loop back it's a little longer walk downhill but very beautiful. A lot of mud this week and snow.
Better known as Green Mountain Park, due to its location, this park in Lakewood (just outside of Denver) is a great (and close) respite from the Denver metro area.
This is the best place to mountain bike in the Denver area (different story once you drive farther west into the mountains). Rooney Valley Trail is my personal favorite at Green Mountain and it's a great adrenaline rush and workout. The views from the top can also make you feel like you're in a different world.
Trail conditions & character
“Views at this park are great on nearly all the trails, and if your after wildflowers in spring this is one of the better places.”
“A very popular spot for locals to hike, trail run, bike, and walk their dogs, but there is usually plenty of parking at its several access points.”
“For mountain biking, it is easy terrain but a steep, strenuous ride that will definitely give you a workout.”
