Kings Canyon is part of the Watarrka National Park in Northern Territory Australia. Although not as popular as some of the other sites in the NT its well worth a visit! Although called kings canyon its actually a gorge 270m height. The walk is only 6km but can take between 3- 5 hours depending on fitness level but even someone whose not in the best shape would still manage it. The 1st half kilometre definitely being the hardest the beginning of the walk known as ' heart attack hill' for its steep incline has an area to stop half way up. once concurred its relatively straight sailing from here with spectacular views of the gorge below and of the surrounding landscape.
