Kakadu is more than a national park. It's also a vibrant, living acknowledgement of the elemental link between the Aboriginal custodians and the country they have nurtured, endured and respected for thousands of generations. Encompassing almost 20,000 sq km (about 200km north–south and 100km east–west), it holds within its boundaries a spectacular ecosystem, periodically scorched and flooded, and mind-blowing ancient rock art.
In just a few days you can cruise on billabongs bursting with wildlife, examine 25,000-year-old rock paintings with the help of an Indigenous guide, swim in pools at the foot of tumbling waterfalls and hike through ancient sandstone escarpment country.
If Kakadu has a downside it's that it's very popular – in the Dry at least. Resorts, camping grounds and rock-art sites can be very crowded. But this is a vast park and with a little adventurous spirit you can easily leave the crowds behind.
