Kings Canyon is a spectacle that is best appreciated from the edge of the sheer cliffs on either side. Take the rim walk, start as early in the day as you can, as it can get very hot here during the day. Take plenty of water, and enjoy the 6km walk in Watarrka National park. The steps that climb the sides of the canyon at the start are guaranteed to get the heart pumping. Make sure you stop for a swim in the Garden of Eden to cool down, though it can be icy cold at this time of year. The “Lost city” domes half way around reminded us of the Bungle Bungles, but the precipitous cliffs on both sides take your breath away as you stand on their edge gazing down the tree-lined canyon floor, some hundred metres below.
