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.

This was definitely harder than the description led me to believe. BUT the trail was beautiful, and the views from Miller Rock were awesome.

Just hiked this trail. I've ridden it a number of times many years ago. Its more technical than I remember with sustained rocky and loose climbs. A few rocky tributary crossing, rocky bridge start, steep loose climb with tech finish. It may be a more of a challenge to people than the description suggests. Just saying. Don't expect a simple ride in the woods. Jun 18, 2017

Just rode this trail today and must report it is far from an intermediate trail. Loose, technical, rocky, but some great flowing sections. The map provided on MTB project does not quite do the trail, and overlapping trails justice. Lots of intersecting forest roads with wrong turns possible quite often. I am not a novice by any stretch, but we managed to get off trail a few times on some jeep/atv trails that were quite loose and rocky and way steep. Sep 17, 2018
