About the location
The entrance fee is quite expensive with around $60 ($30 for children) for the standard tour and for the photographic tour, which is the only one when you are allowed to use a tripid, the costs are around $125. With this tour, you must have a DSLR or mirror less camera, phone photography and children beyond the age of 18 are not allowed for these tours, because they are very limited and they want to make sure that "serious" photographers have a chance to join one of the rare time slots. The Lower Antelope Canyon is a little bit cheaper with $40.
The famous light beams are visible from April to September around 11:30 on clear sunny days.
