Rainbow Bridge National Monument
Rainbow Bridge National Monument was established to preserve and protect scenic, scientific, and historic features in southeastern Utah. Rainbow Bridge is the world’s largest natural bridge and an example of eccenctric stream erosion. The bridge stands 289 feet high (base to top of arch) and spans 276 feet across the river channel. Rainbow Bridge is a sacred place to Native American Tribes. Several archeological sites exist in the monument, and there is evidence that humans have been present in the vicinity for more than 8,000 years. The monument is only accessible by boat from Lake Powell or a 13-mile hike. Glen Canyon NRA and the Navajo Nation border the monument.
