Page, AZ Antelope Canyon consists of two parts – Upper and Lower. The biggest difference between Upper and Lower Antelope Canyon is the size of the canyon itself. The Upper canyon is wider at the bottom vs. the top which is what produces such beautiful light beams inside the canyon. Lower Antelope is much smaller at the bottom, and is shaped like the letter “V.” Upper Antelope Canyon is at ground level so one walks right in (no stairs) and is easier to walk through but also is much darker than Lower Antelope Canyon due to the Upper Canyon being shaped like the letter “A.” Lower Antelope Canyon versus Upper Antelope Canyon is quite a bit harder to walk through as the lower canyon is actually underground, the canyon walls are very narrow in places and there are steep staircases involved in getting around! Again, one cannot explore either unless on a tour. We chose to explore Upper Antelope Canyon today. Our guide today, Marisa, led us through the canyon. She stopped at times to show us Monument Valley, the Heart, Dragon’s Eye and other formations. What makes Upper so stunning is the shafts of light that penetrate the canyon at certain times of the day. Just awesome!
