Created by millions of years of erosion, Antelope Canyon is part of the Lake Powell Navajo Tribal Park, located 10 minutes east of Page, near the Arizona-Utah border in the United States of America. Although it is one slot canyon, there are two points within the park that you can visit: Upper Antelope Canyon and Lower Antelope Canyon. Upper Antelope Canyon is at ground level, has less than a 2% incline, and is the more popular entrance. Lower Antelope Canyon requires walking down (and up) several flights of stairs and ladders.
