Northwest of Fort Collins in the Poudre Canyon area, the Crosier Mountain Trail (#931) is a 5 mile one-way horseback riding route ascending 3,800 feet vertical from 6,400 feet. There are two other trailheads that access Crosier Mountain. The Rainbow Pit Trailhead is located a few miles past the Garden Gate Trailhead - there is a large gravel cut on the south side of the road, a trail sign sits just up the hill from a gate. The third trailhead is also located on County Road 43, by the little village of Glen Haven. The views from Crosier Mountain are beautiful.
To reach the main trailhead, follow SR34 west of Loveland to Drake. Turn right on CR43 for 2.2 miles to the small parking area on the south side of the road.
Overall, Crosier Mountain Trail is the 55th most popular horse trail of all 67 horseback rides in Colorado.
