Stunning natural bridges and ancient Native American ruins, plus magnificent scenery throughout make Natural Bridges National Monument a must see for anyone who has time to make the trip. Sipapu is one of the largest natural bridges in the world, spanning 225 feet and standing more than 140 feet tall. You can take in the Sipapu, Owachomo, and Kachina bridges via an 8.6-mile round-trip hike that meanders around and under them. A 13-site primitive campground is an optimal spot for stargazing. The national monument is about 120 miles southwest of the Needles District of Canyonlands National Park and approximately 45 miles from Blanding.
