Kelly Flats Professional Guide

Detailed Trail Description from our Guidebook

"The trail climbs steeply out of the Cache La Poudre River Valley and winds for a considerable distance across a high ridge with beautiful views of the Mummy Range on a clear day. Noted obstacles include the Chutes and Heart Attack Hill. This high-elevation trail is normally closed mid-November to late May. Open to ATVs but very difficult in places.

Private land developers have built a good road around the Chutes, isolating the Chutes along the side of the road. However, the Chutes are open to anyone looking for a challenge. The Chutes can be easily bypassed. Very steep and rocky in places. Second half of trail can be muddy. Differential lockers and high ground clearance are required. Extremely difficult and narrow getting through the optional Chutes where body damage is likely. The bypass route for Heart Attack Hill has one difficult rocky spot and is nearly impassable when wet."

This is a good intermediate trail. In my opinion is is moderate, not difficult, but is harder if begun at the Kelly Flats Campground. We started on the other end and found it challenging, but with great scenery and areas to picnic or camp. Rated 7.5 to 8 of 10 for difficulty, and 9 of 10 for quality.
