90min tour through the Antelope Canyon with a certified Navajo guide to see red sandstone walls with corkscrew formations, illuminated by sunlight coming down into the slots, which are simply breathtaking.  This colorful canyon is famously long and narrow with a walkable corridor at the bottom of the canyon floor. It was formed by flash floods flowing into the cracks of the Navajo sandstone which was then eroded by wind. Daylight penetrating through the narrow opening at the top creates different kinds of reflected light and colors. Antelope is the most visited slot canyon in the Southwest, partly because it is easily accessible and by far the most publicized, and also since it is so gorgeous and stunning, with just the right combination of depth, width, length, rock color and ambient light that makes this area a popular location for photographers and tourists from all the world.  Entrance fee 50.00
