Molly Dixon was standing on a hill above Nitmiluk National Park, watching the sky turn orange over the sandstone gorges, when she decided she might not be ready to leave the Northern Territory after all. That pull is easy to understand once you spend a day following her through one of Australia’s most remote and remarkable corners, from crocodile-monitored river gorges to thermal hot springs no one else had bothered to show up for that morning. This is solo travel in the wild north at its most unhurried and its most alive.
Nitmiluk National Park sits roughly three hours south of Darwin, covering 292,000 hectares split across two areas: Nitmiluk Gorge in the south and the Edith Falls area, also known as Leliyn, about 90 km north by road. The gorge system itself spans roughly 12 km, flanked by steep sandstone cliffs reaching up to 70 m high, and holds 13 gorges in total. Dixon booked a boat tour to explore two of them.
What lives in these waters
The boat guide covered crocodile biology in more detail than most visitors probably expect. Australia’s two crocodile species share the gorge system under very different terms. Freshwater crocodiles, with their narrow snouts, eat fish and small animals and are largely harmless unless provoked. Saltwater crocodiles are a different category entirely: the largest reptiles on earth, with adult males reaching 4.2 to 6 m, broad heavy snouts, and four exposed lower teeth on each side when their mouths are closed. They are apex predators that treat humans as prey. The park monitors for saltwater intrusion using croc traps, night spotlighting, aerial helicopter sweeps, and river floats. The floats are bitten out of curiosity, and the distinct bite marks confirm whether a large predator has entered the system.
One detail from the tour stuck: a crocodile’s sex is determined entirely by nest temperature during incubation. Nests at 30 degrees Celsius or below produce females. Nests at 32 degrees or above produce males. A middle temperature of around 31 degrees can produce a mix.
The second gorge is open to swimming, but only under close monitoring for exactly the reason described above.
A morning with the hot springs to themselves
The next morning Dixon arrived at the thermal hot springs in the town of Katherine before anyone else. Multiple sections connect along a concrete path, the water pulling gently downstream, every section free to enter. ‘I don’t understand,’ she laughed, ‘because this is a very popular tourist destination. Maybe everyone’s sleeping in, or people have jobs.’
The afternoon brought a different perspective. Dixon booked a 12-minute flight with HeliSpirit over Katherine Gorge, Butterfly Gorge, and the Lily Ponds. The drone restrictions she had been navigating on the ground meant this was her first aerial view of the landscape she had been moving through on foot and by boat. The company runs flights ranging from 8-minute hops to 45-minute wilderness experiences.
The final stop was Edith Falls, the northern section of the park. The campground had sold out by the time she checked, so where she would sleep that night remained an open question she was content to defer. She cooked chicken in her air fryer in the car park, then walked the 2-km return track to the upper falls. The upper pool, she said, was noticeably more beautiful than the lower one and worth every step of the 1 km climb.
A fire extinguisher on the Stuart Highway
Driving that stretch of the Stuart Highway earlier in the day, Dixon passed the spot where, on a previous trip, a fire extinguisher had fallen off a road train traveling in the opposite direction, ricocheted off another car, and come directly at her windscreen at 130 km/h. It dropped at the last second and hit the front of her Hilux instead. The driver of the road train would not have known until he checked the back of his truck. The other driver’s car was a complete write-off, though he was physically unhurt.
By the time she reached the upper falls and turned back toward the car, Dixon was rethinking her whole route. She had originally planned to turn off at Katherine toward Western Australia. A two-week detour to Darwin to meet her best mate Jazz had already extended the itinerary. Now the Northern Territory, a place she had only visited briefly a few years earlier, was starting to feel like somewhere she could stay indefinitely. Going with the flow in Tasmania that year had stretched a planned 10 weeks into 6 months.
The upper falls, still catching light
The upper pool at Edith Falls sits at the end of a 1-km walk from the lower pool, framed by the surrounding bush and open sky.
She walked the kilometre back down, got in the car, and left the question of where to sleep that night, and where to go after that, completely open.
