Trail Information


Castle Rock Gulch Road, FS Road 188, is located within the San Isabel National Forest approximately ten miles east of Johnson Village. This area of the National Forest, commonly referred to as “Fourmile”, contains hundreds of roads and spurs which provide a broad spectrum of outdoor recreational opportunities. Castle Rock Gulch Road is noted for its slick rock outcroppings, broad stream-filled meadows, and twisty road. The rock features offer splendid viewing and photography. This road is popular among OHV users, mountain bikers, hikers, and equestrians. It is a maintained dirt road suitable for all but the largest motorized vehicles (it is not uncommon to see ordinary passenger sedans, minivans, and trucks towing fifth-wheel RVs). Its accessibility to RVs and horse trailers, the multiple outdoor activities it invites, and visual contrasts between stone and green meadows are Castle Rock Gulch Road’s greatest attractions.

Trail is nice and smooth and appears to have just been mostly regraded in areas.

Drove this road after completing FSR 186/Black Dumps. The road is in good condition, seems less wash-boarded than the last time I remember. One MUST be cautious going around the curves! Also, conditions are very dry--the ponds and stream (near Waypoint 4) are almost completely dry.

Ran this after a full day of trails leading an Overland Bound group. Trail is in good condition. Nice alternative to using CR187.
