Wake early to embark on the 1 ½ hour drive south to stunning Litchfield National Park. Here you'll spend the day following walking trails through lush monsoon rainforest and swimming in cool, clear plunge pools. A sealed road links the park's major attractions, however you'll need a 4WD to access the Lost City and the Reynolds River Track. Start your journey at Wangi Falls, where you can have a swim and bite to eat at the café before following the one hour (return) walk to the top of the falls. The cascading twin torrents of Florence Falls offer another spectacular swimming hole, which is accessed via a staircase with 160 steps. There is also a viewing platform at the top of the falls.
Jump in a 4WD drive to see the weathered sandstone pillars of the Lost City, which were formed by thousands of years of erosion and evoke the remains of an ancient civilisation. Or get a bird's-eye view of the Lost City and the tumbling waterfalls aboard a scenic helicopter flight, with options from six to 60 minutes. Back in the car you can drive to see the historic Bamboo Creek tin mine and Blyth Homestead, as well as a field of giant termite mounds, some as large as two metres (6.5 feet) tall. At the end of the day cool off at Buley Rockholes, a series of cascading waterfalls and rockholes, easily accessed from the car park. Spend the night at Litchfield Tourism Park, where you'll find a range of accommodation including a homestead, cabins and campsites, or hop in the car for the drive back to Darwin. On your way back up the highway, stop at the Territory Wildlife Park to get up close to fish, birds of prey, nocturnal animals and reptiles in their natural habitats.
