Antelope Canyon has to be one of the most amazing sights I have ever seen. It is an underground Slot Canyon and stepping inside is like both entering a Cathedral; in that you find yourself in a majestic chamber adorned with delicate glowing colours, and a pinball machine....in that you can just imagine that at any second some mighty and unavoidable boulder will come thundering down the narrow passageway. Depending on time of day these superb shafts of light flood through the Canyon walls making a really colourful spectacle. I spotted this rock formation whilst we walked through, you have to be really fast with your eye as there are many people crowding through at the same time and the visit only lasts about 20 minutes but it is spectacular.
