Into the Northern Territory, where the roads deteriorated markedly but perversely the speed limit went from 110 to 130 km/hr – not that the camper was worth driving at those speeds, 100 was plenty. The landscape of vast flat plains, occasionally interspersed with mesas, covered in low-density, low-height forests and scrub continued. We regularly saw controlled burns keeping the undergrowth in check, only once having the highway completely engulfed in smoke.

Posted observation points were welcome, they helped to break the driving. This one just short of Victoria River had a bonus walk up a hill in the sweltering heat.

Trees and rocks, with a bonus river.

Down to the roadhouse, with attached campground, the only facilities for many miles.

Said roadhouse, without all the vehicles belching diesel. Saw a bunch of big motorsport team trucks rolling through, a change from the preponderance of mining and cattle road trains. Found later the Supercar roadshow was moving from Perth to Darwin.

After not having seen a supermarket all week, a restock in Katherine was needed before heading to Nitmulik National Park for a couple of nights. The Three Gorge boat tour gave us the opportunity to sit, occasionally walk to another boat and learn about the gorge from a local. Towering cliffs and how the volume of water in the wet season has shaped the landscape were impressive.

This may be recognised from some films, but not by me.

Somewhat inexplicably to me, we had an hour to swim at Lily Ponds under a tall thread of a waterfall. About a third of the group got in the water, most else sat in the shade.

I found a marked track that involved plenty of rock-hopping and steep scrambling to the top of the waterfall. Much better view and more interesting up there.

The creek approaching the cliff.

Spot the tour group.

Further up the gorge, past where boats can reach – there are a lot of rocks around these parts.

On the return, the longer walk (not long) between boats and impassable rocks.

First crocodile in the wild for the trip.

Our guide pointed out a viewing platform up high as we neared the end of our boat trip, suggesting it was a good place to see the sunset. As it was the first time I’d seen significant clouds in the sky since our layover in Melbourne, I was hopeful it would be worth the walk and steep staircases. It was.

But first, different rocks! Curious conglomerations.

The start of the Kakadu Highway held the most engaging driving of the trip – especially in a seven metre long, three metre high van. Alas that didn’t last long, but probably good for Mum’s comfort and getting to Jabiru campground before dark. I was a bit under the weather for our two days there, unfortunately coinciding with the hottest weather of the trip – alarmingly close to forty degrees Celsius.

Better than your average water tower.

A little boat tour up the East Alligator River (no gators in Australia, only crocs – the river mistakenly named) was slightly cooler than staying on land. I found the local guide interesting, plenty told of how the local flora and fauna form part of their life. Not a lot of wildlife to be seen in the heat of the afternoon; more time in Kakadu and even getting into the vast, sparsely populated Arnhem Land would be cool.

Spot the fictional characters – Homer, E.T., Robocop…

Although not that far back to Darwin and campervan return, certainly less distance than we had generally been driving, we broke it up choosing to stay in the middle of nowhere. Bark Hut Inn had a great campground, adjoined to a roadhouse, built in an area that once was predominantly buffalo and croc hunting (the old modified Landcruisers with a lot of external steelwork looked plain mad). Disappointed by the lack of wildlife on the trip thus far, we booked one last boat tour on the nearby Corroberee Lagoon – thinking we had enough time to pack, clean the camper and drive to Darwin the following day.

It turned out to go swimmingly (except no-one literally went swimming for obvious reasons). An exceptional tour with a very knowledgeable guide who was only too happy to answer questions, show us what we wanted to see and keep us both amused and informed. Helped that we saw plenty too – here’s a little of it:

On that high, the campervan was returned on time leaving us a day and a bit to have a look around Darwin. With the Supercars in town for the weekend, the excellent night market at Mindil Beach was packed – but the city seemed deserted the following day. Perhaps it’s always like that, but it seemed an odd place. Give me the wilderness instead.
