Rainbow Bridge National Monument protects one of the world's largest known natural bridges, standing 290 feet high and spanning 275 feet across. This magnificent sandstone arch was carved by flowing water over millions of years and is considered sacred by several Native American tribes including the Navajo and Hopi. The bridge is accessible only by boat across Lake Powell or by challenging overland hikes through rugged desert terrain. It is managed by the National Park Service.
