Introduction to Lower Antelope Canyon: Lower Antelope Canyon is called "Hasdeztwazi" in Navajo; it means "arch-shaped spiral rock" and is not open for about nine months of the year. Located underground, you need to climb metal stairs deep into the ground, and you may also need to rely on some ropes to complete the Lower Antelope Canyon. Due to its relatively high difficulty of entry, there are fewer tourists. But photographers often take pictures here. The entrance is only one person wide and at the same height as the ground, making it unrecognizable from a distance. After entering, it drops sharply for about 50 meters. The total length is very long. Generally, tourists are only allowed to go to the halfway point. The valley of Lower Antelope Canyon changes a lot, and some passages are not high enough for people, so tourists may hit their heads.
