First off, I visited in the morning (around 9am) in December 2015 and my review is based on the lighting during that time in the canyon.
- it's beautiful!
- easier walk-through than the Lower Antelope Canyon
- it was quite dark in there so only professional cameras can capture nice photos. It's much brighter inside the Lower Antelope Canyon
- depending on how the sunlight comes in the crack, you may or may not see the "orange" tone of the stones. I didn't see much of the orange stone, I saw mostly gray because it was too dark. Much easier to catch the beautiful colours on the stone at Lower Antelope Canyon
- one way in, same way out. It's basically a 2-way traffic so getting photos is hard and you don't get much time to enjoy the scenery. The Lower Antelope Canyon is a 1-way traffic so it's a bit better.
- wear a face mask to minimize breathing in the tiny red dust
- wear good shoes (it's all sand)
- if you're a photographer or don't have a great camera, don't bother taking too many pictures! Just enjoy the moment :)More
