Rainbow Bridge, on the edge of Lake Powell, is the largest natural bridge in the world at 290 feet/88 meters tall and 270 feet/83 meters across. Rainbow Bridge is considered sacred by the Navajo culture as a symbol of deities responsible for creating clouds, rainbows and rain - the essence of life in the desert. Read more...
One of the natural wonders of the world, the bridge has been formed by erosion of the sandstone by water flowing from Navajo Mountain towards the Colorado River. The bridge was officially "discovered" by the Douglas-Cummings surveyor party in 1909. Until the formation of Lake Powell, the bridge was several miles up Bridge Canyon from the shores of the Colorado River, and it was one of the most remote and inaccessible regions in the United States. Today, the shores of Lake Powell, which flooded Glen Canyon, now bring boaters to its base.
Rising up at the edge of Lake Powell, it may be reached by boat, on foot, or on horseback. Rainbow Bridge is located 50 boat miles northeast of Wahweap Marina. Boat cruises from Wahweap or Bullfrog Marinas are offered daily. Except for a courtesy boat dock there are no services.
Trailheads to Rainbow Bridge may be reached via unpaved roads on the Navajo Indian Reservation south of Lake Powell. Hikers must have a permit from the Navajo Nation. The most commonly used trails are the 14-mile trail from the Navajo Mountain Trading Post or the 13-mile trail from the abandoned Rainbow Lodge. Scenic flights over Rainbow Bridge can be arranged at Bullfrog and Wahweap. The best times to hike are April, May early June, September and October.
The daily average temperature at the bridge during the summer is 100 degrees Fahrenheit, 37.7 degrees Celsius. Temperatures in the spring and fall are moderate, 75 degrees Fahrenheit, 23.8 degrees Celsius.
