Castleton Tower is a 400-foot (120 m) Wingate Sandstone tower standing on a 1,000 foot Moenkopi-Chinle cone above the northeastern border of Castle Valley, Utah. The Tower is world-renowned as a subject for photography and for its classic rock climbing routes, the most famous of which is the Kor-Ingalls Route featured in Fifty Classic Climbs of North America. Castleton Tower can be accessed by a trail that begins south of the tower at a primitive camp ground.
