This Arizona slot canyon has reached legendary status in the landscape world. Carved by centuries of rushing water, the striated rock walls flow like colorful ribbons of silk. In many cases, these curving passages take the shape of spiritual beings. History & Nature Antelope Canyon is the product of millions of years of water erosion. In fact, the Navajo name for Upper Antelope Canyon is “Tse' bighanilini,” which means "the place where water runs through rocks." Once home to herds of pronghorn antelope, the canyon now lies within the LeChee Chapter of the Navajo Nation, and draws nature-lovers near and far for its remarkable, mysterious beauty. The canyon walls climb 120 feet above the stream bed, making it a cathedral of red-hued, swirling sandstone. Things To Do Exploring this natural wonder is encouraged, but guided tours are required. There are several authorized tour operators to choose from who will not only bring you to the canyon, but also give you a breadth of information about the history, geology, and culture of the Antelope Canyon area. Photographers will enjoy snapping photos, but the famous light beams are not always visible. Beams occur most often during the summer, with the best views between late March and early October.
