My husband and I visited Antelope Slot Canyon for out anniversary. Needless to say, it was amazing! The walls of the canyon and the colors are almost surreal. The morning to mid-day light creates beams of light, from the ceiling to the floor. The afternoon makes the walls look like they are on fire! We took the 2 hour tour, which is the longest. You'll need every minute of that tour to take everything in. This place will leave you speechless, which is good, because it almost cleanses your mind!
