The Grand Canyon is in northern Arizona, and is one of the great tourist attractions in the United States. The massive canyon encompasses several distinct areas, most famous of which is Grand Canyon National Park, a United States national park and WV-Unesco-icon-small.svg UNESCO World Heritage Site. Visitors to the national park have many options, including: the remote North Rim; the more accessible (and therefore more crowded) South Rim; parts of the canyon, such as Phantom Ranch or the Colorado River, upon which many boating trips are made. In addition, parts of the southwestern end of the canyon are within the borders of two Indian reservations: the Havasupai Indian Reservation and the Hualapai Indian Reservation (which includes the development known as Grand Canyon West). Lastly, part of the southeastern end of the canyon is within the borders of the Navajo Nation. Except for the Navajo Nation portion, all sections of the canyon offer amenities for visitors. However, the national park, and in particular the South Rim, is by far the most popular destination and the best equipped to handle the millions of yearly visitors.
