Kings Canyon, Australia.

Kings Canyon is part of the Watarrka National Park in Northern Territory, Australia. Travelling at the western end of the George Gill Range, it is 323 km southwest of Alice Springs and 1,316 km south of Darwin.
The walls of Kings Canyon are over 300 metres high, with Kings Creek at the bottom. Part of the gorge is a sacred Aboriginal site and visitors are discouraged from walking off the walking tracks.

Two walks exists at Kings Canyon. The 2 km and approximately 1 hour Kings Creek Walk traces the bottom of the gorge. At the end of the walk is a platform, with views of the canyon walls above. The 6 km and 3-4 hour Kings Canyon Rim Walk traces the top of the canyon. A steep climb at the beginning of the walk, which locals call “Heartbreak Hill”, takes visitors up to the top, with spectacular views of the gorge below and of the surrounding landscape. About half way during the walk, a detour descends to Garden of Eden, a permanent waterhole surrounded by lush plant life.
