A World Heritage Site, Uluru is an awe-inspiring sandstone rock formation rising out of the desolate outback of Australia’s Northern Territory. The name derives from the aboriginal tribes that settled in the area 10,000 years ago. The landmark is also known as Ayers Rock, named in honor of Sir Henry Ayers, who served as Chief Secretary of South Australia in the late 19th century. Jutting nearly 1,150 feet in the air, the natural monolith is taller than the Eiffel Tower, and stands in stark contrast to the miles of flat desert that surround it. Visitors can climb to the top of Uluru (the hike takes anywhere from 30 minutes to two hours) and explore the base, which is about six miles around. The view atop the rock is remarkable during sunrise and sunset.
