Rainbow Bridge, located at the edge of Lake Powell, is the largest natural bridge in the world. It is 290 feet from its base to the top of the arch, and it spans 275 feet. Natural bridges are rare, and differ from arches in that they form when a watercourse breaks through rock. Initially, water flowing off nearby Navajo Mountain meandered across the sandstone, following a path of least resistance. A drainage known today as Bridge Canyon was carved deep into the rock and the stream flowed in a tight curve around a thin fin of soft sandstone that jutted into the canyon. Rainbow Bridge was created when the force of the stream eventually cut a hole through the fin and flowed directly through the opening, enlarging it over time. Rainbow Bridge is accessible only by boat or by a 13 mile hike (with permit from the Navajo Nation). Boat trips to the bridge may be made in private, rental, or tour boats. A courtesy dock is available for short-term docking while people make the 1.5 mile walk to the bridge. By boat, it is approximately 50 miles from Wahweap, Bullfrog, or Halls Crossing.
NOTE: Always take adequate precautions (such as prodding with a stick and/or wearing gloves) before reaching into dark crevasses and holes in the wild. Before you set out read the waiver of responsibility and disclaimer.
