Australia: Windjana Gorge National Park

Windjana Gorge National Park is an eroded 300 million years old limestone underwater reef that since has been uplifted. Colorful eroded cliffs and rocks. And tons of wildlife as you hike along the gorge – freshwater crocodiles everywhere, flying foxes bats roosting in the trees (they are worth a separate post since I spend 2 hours watching them), and many birds.
