A fun intermediate out-and-back near Allenspark.
A fun lollipop trail that climbs to Miller Rock, a beautiful viewpoint. While the trail is not very technical, it does have a couple of narrow sections traveling high above South St. Vrain Creek where a mistake would be unpleasant (trust me, I've been there, done that). I'd recommend riding the loop at the top in a counterclockwise direction. There are sweet views into Indian Peaks and Rocky Mountain National Park if you gain Miller Rock at the top of the ride.
