Kings Canyon, Natural canyon in Watarrka National Park, Northern Territory, Australia.

Kings Canyon, also called Watarrka, cuts through Mereenie Sandstone in the George Gill Range. Its sheer walls rise over 100 metres, with reddish-brown banded rock faces and pale streaks. Below the rim, Kings Creek runs along the floor, and the surrounding plateau is dotted with rounded sandstone domes.

Luritja people have lived in the area for at least 20,000 years. Ernest Giles reached the canyon in 1872 and named Kings Creek after his friend Fielder King. The canyon was listed on the Register of the National Estate in 1986.

The Luritja and Arrernte name for the creek and canyon is Watarrka, from the Luritja word for the umbrella bush (Acacia ligulata) growing here. The Garden of Eden waterhole is a men's sacred site with Dreaming stories, so swimming is not allowed; the Kings Creek Walk ends at a platform before the sacred section.

The Kings Canyon Rim Walk extends 6 kilometers (3.7 miles) around upper edges, offering views across desert landscape and access to the Garden of Eden, a fern-covered amphitheater with natural pool.

The area supports 572 plant species, including 60 rare varieties, and provides habitat for 80 bird species that nest in rock crevices and feed near waterholes.
