Detailed map of the Black Canyon National Water Trail within the Lake Mead National Recreation Area. The water trail comprises 25 miles of the Colorado River between Hoover Dam and Eldorado Canyon along the Arizona-Nevada border. This section of river is a paddler’s paradise of clear cold water, hot springs, beaches, coves, and caves through the rugged Black Canyon. The Black Canyon National Water Trail was designated by the National Park Service in 2014 and is the first national water trail in the southwest and the first to flow through a desert.
