Keg Knoll Road is an awesome spur off of Lower San Rafael Road. Although the trail itself is nothing spectacular, the ending is worth it all! Camping on the end of this trail is among the best around, and it is also the hiking trailhead to Colonnade Arch (a.k.a. Five Hole Arch). This amazing but seldom visited sandstone arch overlooks the Green River, Colonnade Arch (a.k.a. Five Hole Arch). Keg Knoll Road is a must-do if you are exploring the area!
