Corroboree Billabong, Marrakai NT 0822, Australia
The Mighty CorroboreeJust over 60 miles from Darwin at the edge of Kakadu National Park, the Corroboree Billabong is a healthy arm of the Mary River Wetlands known for white-bellied sea eagles, kingfisher, barramundi fish and the largest concentration of saltwater crocodiles ("salties") in the world. On an open-air boat, wildlife enthusiasts can cruise among the lotus lilies and mangrove forests in search of such unique wildlife as black-neck storks (known as jabiru in these parts) and the largest terrestrial predators on Earth. Depending on the water temperature, you might find a salty warming its cold-blooded body on a river bank; but when the water warms, don't be surprised if one sneaks up on your boat as if it were stalking Captain Hook. We warned you.
