Welcome to the Greyhills Academy High School website. We are a grant school under the direction and management of the Bureau of Indian Education. You’ll find us located on the beautiful Navajo Indian Reservation in Tuba City, Arizona. We are approximately one hour north of Flagstaff and 50 miles east of the Grand Canyon. We educate over 340 students in 9th through 12th grades. We are passionately committed to the preservation of the Navajo culture and use that as a foundation for teaching the academics.
