Antelope Canyon Tours specialize in taking people on tours of the canyons around Page, Arizona and Lake Powell. The tour begins at Lake Powell Boulevard. The Antelope Canyon, also called Corkscrew Canyon, are almost like sculptures in stone...completely awe inspiring. These are called slot canyons and have been created by gushing river water. Many of them are not even a yard wide, but are hundreds of feet deep! Only authorized guides are allowed to take tours.
