Kakadu is the largest national park in all of terrestrial Australia, covering an impressive 20,000 square kilometres of the Territory. Consequently, within its boundaries is an eclectic array of environments, from floodplains to woodlands, paperbark forests to impossibly high stone escarpments, all sheltering a diverse collection of wildlife. The most well-known area is arguably Jim Jim and Twin Falls, a pair of waterfalls near the Garnamarr Campground that flow steadily during the tropical summer.
