Arches UK - a collection of Nature’s arches and bridges
The largest natural bridge in the world and one of the largest arches - ranks 3rd. It spans Bridge Canyon off Lake Powell. The bridge has a span of 275 feet and a height of 246 feet. The easiest way to get to Rainbow Bridge is to take a 7 hour boat trip from Wahweap Marina near to Page Arizona. However, the lake levels have fallen so much that it now needs a mile and a half walk from the boat dock to the bridge. This aerial photo shows how much closer the boat dock used to be. Alternatively, it is possible to backpack around Navajo Mountain a distance of 13 - 14 miles.
