Fun, intermediate mountain bike ride about 20 minutes west of Denver, near Lakewood, Colorado. This trail is fairly easy with a good climb and intermediate descents.

Close to home trail for me, one of my favorites. I did come across two giant rattlesnakes 10-9-16 so keep an eye out. Not much coverage from trees (none) but still some solid trails for running, hiking, or biking.

I did a portion of this trail on mountain bike and it was definitely a workout. Be careful as there's a mix of hikers and bikers- some of the ridge walking is steep!

I loved it. I would hike the 6.5 mile Green Mountain Trail again. It had everything for me, which included beautiful scenery and a trail equal to my physical conditioning.

Good trail. Little tree cover and some heavy traffic at the start but thins out as you go. Watch for the mountain bikers though: a bit unruly on this trail.

Went up the steep climb to complete a 2.2 mile run to the cell tower and back down. The traffic is usually light, but can readily become heavy with runners and bicyclists.

Nice, steady uphill grade. Fairly wide trails making passing other hikers easy. Overall, the hike was pretty easy. Go during the weekdays to avoid crowds. The summit loop on the northside can tricky for those with bad knees coming down (steep in a few spots with lots of loose rubble).

Trail is in great shape. Perfect trail running location for accessibility to the front range and for views of the city and Red Rocks

First timer. Enjoyed doing something new and loved the scene. Weather was perfect today @75 and a nice breeze. Next time I'll do the who loop. Parked on W Alameda at the dog park and took off. Enjoyed this. Walked and jogged this trail.
