Located at the “Red Center” of Australia, this national park has incredible significance to the aboriginal Anangu, who work with the Australian government to preserve and maintain these 210 square kilometers (130 square miles) of land. It is known for two landmarks that have come to define not only this arid stretch of land, but the entirety of Australia; Uluru (Ayers Rock) and Kata Tjuta (Mount Olga). A massive slab of sandstone (348 meters/1,142 feet high), Uluru is famous for changing colors under various circumstances, flaring a deep red during sunset and sunrise. Tjuta is a conglomerate rock formation located 40 kilometers (25 miles) to the west, rising 1,066 meters (3,497 feet) above sea level. The Anangu forbid climbing these treasured spiritual landmarks. Park entrance is A$25 (about $25.50 USD).
