Natural Bridges National Monument protects three massive natural stone bridges carved by flowing water over millions of years. Sipapu, Kachina, and Owachomo bridges represent different stages of natural bridge formation and are among the largest in the world. The monument also preserves Ancestral Puebloan ruins and petroglyphs, and was designated as the world's first International Dark Sky Park. It is managed by the National Park Service.
