More technical than strenuous, some very rocky sections.

Just West of Loveland off of 34, this trail is an interesting diversion. It follows a hogback, and some of the trail is build on layers of off-camber, crumbling sedimentary rock.

You'll ride Indian Summer and Blue Sky on this loop as well.


Devils Backbone Trail starts as an easy gradual climb from the free parking area north of Highway 34. Go around the footbridges using the bypass trails and travel through a fence. The trail continues to climb with a few small rock obstacles.

Stay to the right at the first split (hikers only to the left). Stay to the right where the trails meet back up and climb a steep hill with a few switchbacks and water bars. Most riders will have to push up a few of the technical sections.

3/4 of the way up the climb the trail splits. Stay to the right (hikers and horses to the left) and the trails rejoin in 1/2 a mile or so. The trail then turns into a gradual climb with a few rocky sections.

The trail splits again at around mile 2.5. Both trails are very rocky however the trail to the right (east) is more difficult and will require most riders to push a few sections. The trails meet back up after 1/2 mile or so and climb to the top of the ridge.

You'll then ride a portion of Blue Sky. This trail is less technical, and flows very well. Most riders will thoroughly enjoy this fun section of the ride. Finally, you'll hook up with Indian Summer loop. This one is also smoother singletrack with less extreme pitch - great for intermediate riders.

Once you round the loop, you'll head back down and retrace your steps.
