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.

I particularly like hiking here in spring, when it is less crowded.

A great trail for children and dogs - tons of options for distance ranging from a couple miles to 20+ miles.

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.
