Which two Indian reservations are located adjacent to the Grand Canyon?

The two Indian reservations located adjacent to the Grand Canyon are the Hualapai and Havasupai reservations. The Hualapai Tribe manages a portion of the western rim of the Grand Canyon and is known for attractions like the Grand Canyon West and the Skywalk. The Havasupai Tribe resides in a remote canyon and is famous for its stunning waterfalls, including Havasu Falls, which draw many visitors each year.

The other groups listed, such as the Navajo and Tohono O'odham, are located in areas that are further away from the Grand Canyon itself, and while they have significant histories and cultures, they do not border the Grand Canyon. Similarly, the Pueblo and Hopi tribes, although culturally rich and important, are situated in different regions of Arizona and do not have reservations adjacent to the Grand Canyon. The Blackfeet and Lakota are affiliated with areas in the Northern Plains, far removed from the Grand Canyon region. Thus, the Hualapai and Havasupai reservations are correctly identified as the two adjacent to the Grand Canyon.
