I booked tour to Antelope Canyon more than a month ahead of our trip and only a few places left at that time. This is such awesome place but conditions to viist it is quite difficult. Too much people but when you are inside you just admire how nature creates such a beauty. In the afternoon we drove through Monument Valley to our next destination in Utah. Unfortunately there was sand storm and we could not see much. Need to come back to Arizona one day to see it in details.
