The name of each bridge was derived from a Hopi Indian term that described its characteristics. The Sipapu Bridge, the longest and highest, is 268 feet long, 31 feet wide, 53 feet thick and 220 feet high. The second largest natural bridge in the world, Sipapu represents a mature stage in the evolution of natural bridge formation.
Kachina Bridge, 2.5 miles away at the junction of Armstrong and White canyons, straddles a stream bed at a height of 210 feet. The most massive of the three, Kachina is 204 feet long, 44 feet wide and 93 feet thick. Owachomo Bridge, the smallest and oldest, is a narrow strip of rock only 9 feet thick in the center and 27 feet wide. Spanning 180 feet, Owachomo is in a late stage of erosion and is heading toward the day when weather and gravity will bring it crashing to the canyon floor.
All three bridges are accessible by short hikes off Bridge View Drive, a scenic, 9-mile (one way) loop drive that begins and ends near the monument visitor center. A trail leads down to each bridge, and an 8.6-mile (round trip) trail connects the bridges. Horse Collar Ruin, an ancestral Puebloan cliff dwelling, is visible from the Bridge View Drive overlook. Pets and bicycles are not permitted on trails or off-road areas. Hiking on the bridges is not permitted.
Camping is available, but there is a 26-foot limit for RVs and any vehicles pulling them and the closest gas stations are in Mexican Hat, 44 miles south, and Blanding, 38 miles east.
