Supai

"Supai is the village you need to cross through to reach the waterfalls and campgrounds. It is located about ~2 miles from the campground. The village is home to a few hundred people, who accommodate tourists every week as they travel to reach the waterfalls and campgrounds. The village relies on tourism as their main source of income. It is the only occupied settlement in the Grand Canyon (however, it is not part of Grand Canyon National Park). Supai has its own post office, school, lodge, convenient store, and police station. There are no roads and all the supplies for the village is either carried down into the town by pack mules or via helicopter. Because of how remote Supai is, it is not a good idea to plan on stocking up on food and gear in town as everything is super expensive."
