Castleton Tower, Rock climbing landmark in Castle Valley, United States

Castleton Tower is a sandstone formation in Grand County that rises approximately 400 feet above a cone-shaped base and is visible from many miles away. The tower offers numerous climbing routes of varying difficulty that can be reached from the surrounding valley floor.

Layton Kor and Huntley Ingalls made the first ascent on September 16, 1961, via the route now rated 5.9 and named after them. The Kor-Ingalls Route appears in Fifty Classic Climbs of North America. Climbing historian Stewart Green estimates more than 40,000 successful ascents, with named routes now on every aspect of the tower.

The tower's name comes from its resemblance to a castle keep, and its most famous route, the Kor-Ingalls, is listed in Fifty Classic Climbs of North America. Climbing historian Stewart Green estimates more than 40,000 successful ascents, and named routes now exist on every aspect of the tower.

The trail to the tower begins at the Climber's Campground south of the formation, reached via Castleton Road off Route 128 along the Colorado River. The 221 acres around the base, including the campground, are owned and managed by Utah Open Lands. The nearest town is Moab, about 10 miles southwest.

In 1964 and again in 1973, a car and a female model were lifted to the summit in several sections by helicopter for two Chevrolet TV commercials. The vehicle was reassembled, filmed by a chopper crew, then disassembled and removed, model included.
