This was an excellent hike. No one on the trail; and it was very scenic.
The trail guide, and the signs at the trailhead are wrong about the elevation gain. The GPS I had, recorded a starting elevation of 6650 and an elevation at the summit of 8015 ft. This was a 1362 ft gain over 1.8 miles, not the 850 ft gain listed. No big deal, but it was inaccurate.
The Trails Illustrated Map for the Cache La Poudre/ Big Thompson, # 101 is also inacurate. It shows that there is one trail head, but in reality there are two. One at the campground / bathroom, which heads to the Kreutzer Nature Trail and then to the west side of the Mt McConnel tral, and another near the bridge, which goes to the east side of the McConnel trail.
Consult the map at the fee pay station.
The hike from the parking lot goes up fairly quickly, but from the summit heading back to the road at the bridge it is much more difficult and more primitive. Not too bad, but it required more focus and I would not attempt this in anything other than good hiking shoes. It actually took longer coming down than going up, which was surprising.
All in all, this is a great hike, less than an hour away from Fort Collins.
