This beautiful park lies just 122 km (76 miles) south of Darwin off the Stuart Highway. Its 1,340 square km (515 square miles) are an untouched wilderness of monsoonal rain forests, rivers, and striking rock formations. The highlights are four separate, spectacular waterfalls—Florence, Tjaynera, Wangi, and Tolmer Falls —all of which have secluded plunge pools (The pools are suitable for swimming but occasionally there are crocs here, so observe any "no swimming" signs). There is also a dramatic group of large, freestanding sandstone pillars known as the Lost City, and the Magnetic Termite Mounds, which have an eerie resemblance to eroded grave markers, dot the black-soiled plains of the park's northern area. You'll need to camp if you want to stay in the park; campgrounds and RV sites are near several of the major sights (call the Parks and Wildlife Service of the Northern Territory at 08/8976–0282 for information). There are also a few restaurants and a modest hotel (the Batchelor Resort [08/8976–0123], which has comfortable hotel rooms, as well as RV and camping facilities) in the nearby town of Batchelor.
