Last year in August, I visited this place .Breathtaking. Its in the Navajo land so make sure to do the booking before going to Page AZ.Antelope Canyon tours and there are many other availaible.Always go there in the middle of the day when the sun is on the top of your head to unravel the full potential of the canyon. early morning and post afternoon is fine but that time beam doesnt enter the canyon and you will see colors but not as bright and as vivid during the middle of the day.
