Both trailheads are easily accessible and this trail can be traveled either way. Loop hikes including FDR 110 require a walk of about 5 miles along the road. This trail is suitable for foot, mountain bike, and horse travel. Wildlife that may be encountered include deer and elk, badgers, Coopers and Red Tailed Hawks. It is best traveled from the top down.
Trail use is light throughout the summer and moderate during the big game hunting seasons.
The rocks on either side of this north-trending ridge have been dropped down by faults making Castle Valley Ridge what geologists call a horst. Cattle graze this area during summer. During the summer lightning poses a hazard along the ridge tops especially during the afternoon hours. Any drinking water obtained along the trail should be appropriately treated before use.
