Bright Angel Canyon is surrounded by the brilliantly colored Redwall Limestone. There are few more dramatic sights in the world than looking down over 5000 feet into the depths of the Grand Canyon. It is confusing, but the Bright Angel Canyon and Bright Angel Creek run into the Colorado River from north to south. The trail that follows the Canyon is the North Kaibab Trail. The Bright Angel Trail is on the South Rim not in Bright Angel Canyon. The North Kaibab Trail descends 14 miles where it joins the South Kaibab Trail. Surprisingly, the Trail is extremely steep as it comes off the Rim but most of the milage is on almost level terrain.
