Rainbow Bridge National Monument, located in southern Utah, is another famed geological formation in the area. Aside from multi-day hikes, the only way to see this large, sandstone, natural arch is by a boat ride on Lake Powell. Various tours depart from the two marinas in the Glen Canyon Recreational Area near Page, Arizona. Once you reach the area from the lake, there is a one-mile hike to the arch. Tours vary in length depending on the other offerings of the boat trip.
