Supai is a census-designated place in Coconino County, Arizona, United States, within the Grand Canyon. As of the 2010 census, the CDP had a population of 208. The capital of the Havasupai Indian Reservation, Supai is the only place in the United States where mail is still carried out by mules.
Despite the fact that the Grand Canyon is one of the most visited locations in the United States, nearby Supai Village is visited much less often. The tribal centre of the Havasupai Tribe, Supai is a remote village located in the southwestern branch of the canyon. Tourists are welcome at the protected reservation, but it takes a rugged 8-mile hike or horseback ride unless you can snag a helicopter.
Havasupai means “People of the Green Blue Waters” in reference to the four beautiful waterfalls to be found along the Havasu Creek. The waterfalls serve as the community’s water source. The 208 permanent residents get their mail via mule.
