There are many reasons to visit The Kimberley: The Bungle Bungles, Horizontal Falls and incredible helicopter rides over massive waterfalls, to name a small fraction. But a place that you probably haven’t heard about is Dimalurru (Tunnel Creek).
What is Dimalurru (Tunnel Creek)?
About 350 million years ago, the Dimalurru (Tunnel Creek) was underwater, forming part of an ocean reef system. These days, the water level has dropped, but not before carving a huge 750-metre limestone tunnel that gets up to 20 metres high and 15 metres wide in some parts. It’s Western Australia’s oldest known cave system.
Besides its ancient history and incredible natural beauty, this is also a place of significant Australian history. In 1897, it was used as a hideout by the famous/ infamous (depending on who you ask) Bunuba Indigenous leader and freedom fighter of the time, Jandamarra .

Why explore Dimalurru (Tunnel Creek)?
Dimalurra travels from one side of the Napier Range to the other. And as beautiful as the range is from above, there’s an entirely different type of beauty below.
Wander through large caverns, with beams of sunlight leaking in from the world outside. Large stalactite formations hanging down from the roof add to the drama, as do mini-waterfalls along the tunnel wall. Also, keep an eye out for Indigenous rock art near both entrances of the tunnel.
Along the way, you’re likely to spot many different bat species and even freshwater crocodiles that call this cave home.

How to explore Dimalurru (Tunnel Creek)
Napier Range and Dimalurru reside in the West Kimberley, about 2.5 hours (180 kilometres) east of Derby. Head out yourself and take part in a day of hiking. Be sure to wear comfortable shoes that can get wet, and bring a torch (a real one, your phone torch light won’t cut it) as the tunnel gets pitch black in places.
If you don’t want to go it alone, join day trips from Derby, Fitzroy Crossing and Broome.

WA might be enormous, but the right insider knowledge brings its mysteries a whole lot closer.
“Western Australia is a land of record-breakers,” says Carolyn Tipper, a Travel Director working on AAT Kings Western Australia tours. “It has the second-longest fault line, the second-largest meteorite crater, the second-fastest flowing river—it just keeps surprising you. And every area has its charm.”
From tropics to deserts, Australia’s largest state is a land of extremes. You can’t see all of Western Australia in a lifetime, but with the right guide, you can discover its hidden pockets of magic.
Carolyn wishes to reach her guests’ hearts. “I want them to enjoy and be in awe,” she says. “I want them to have the holiday of a lifetime.”
1. Mimbi Caves
You wouldn’t expect a Great Barrier Reef in the outback – but that’s what you’ll find at Mimbi Caves. Once part of a 350-million-year-old reef, these caves hold marine fossils, ancient Indigenous rock art, and Dreamtime stories shared by a Gooniyandi guide.
“That’s when the real connection happens,” says Carolyn, who has taken guests through on the AAT Kings Wonders of the West Coast and Kimberley tour. “When guests connect, not just with the land, but with the people who have called it home for tens of thousands of years.”

2. Kalbarri National Park
Nothing prepares you for the Kalbarri Skywalk: a 25-metre platform jutting over Murchison Gorge, 100 metres above the red cliffs and river below. From July to October, join the AAT Kings Untamed Pilbara and West Coast tour to see over 1000 wildflower species paint the park, and listen as an Indigenous guide shares their uses, bush foods and medicine plants.
“I want our guests to have an emotional experience,” says Carolyn. “It’s not just about seeing the land, it’s about stepping into the stories.”

3. Hamelin Bay Wines
Margaret River isn’t just a top wine region – it’s a winner in every category. Where the Indian and Southern Oceans collide, granite cliffs rise, limestone caves sprawl and Karri forests tower. It almost distracts from the world-class Cabernet Sauvignon and Chardonnay.
Almost.
Out of over 100 cellar doors, AAT Kings pick Hamelin Bay Wines as a favourite. Hosted tastings of small-batch wines on the Western Wonderland tourend with a group meal. The menu shifting with the seasons.
“Get off the beaten track to one of WA’s most relaxed venues for some amazing red and white signature wines,” explains Carolyn, “accompanied with upmarket pub food.”
Spectacular views.

4. Wildflower Guided Walk, Kings Park
Western Australia is home to 12,000 native plant species – 3000 bloom in Kings Park’s Botanic Garden. Stroll past Kangaroo Paw, Banksia and blooms from the Goldfields, Stirling Ranges and Kimberley. “The diversity of Western Australia is immense,” says Carolyn, who leads guests through on the South Western Escape tour.

5. Hoochery Distillery
Did you know that between Kununurra and Emma Gorge lies the state’s oldest continuously operating distillery? Well, the oldest legal one. Set on a family farm, Hoochery Distillery was hand-built using materials found on the property, conjuring up award-winning rum from local sugarcane, wet season rainwater and yeast.
Today, visitors cansample a hearty nip of rum, along with whiskies and gins – all crafted using traditional, labour-intensive methods. It’s the ideal way to soak up the ‘spirit’ of the Kimberley on the AAT Kings’ Untamed Kimberley tour.

6. Geraldton
The wildflowers of the Midwest will make your heart blossom. In Geraldton, the Helen Ansell Art Gallery brings the region’s botanicals to life in vivid colour and intricate detail. In nearby Mullewa, wander bushland trails lined with everlastings and native blooms. Further afield, Coalseam Conservation Park bursts into carpets of pink, white, and yellow each spring. Do it all on the Wildflower Wanderer tourwith AAT Kings.

7. El Questro
Wake up after a night under the stars at Emma Gorge Resort, ready to explore the mighty beauty of the El Questro Wilderness Park. With deep gorges, thermal springs, and cascading waterfalls, time slows here.
Join the AAT Kings’ Wonders of the West Coast and Kimberley tour to drift through Chamberlain Gorge, where sheer sandstone walls glow burnt orange in the sun, archer fish flick at the surface, and rock wallabies peer down from ledges above. Then, step into Zebedee Springs, a secret oasis of warm, crystal-clear pools among prehistoric Livistona palms – a moment of pure, wild stillness.

8. Lake Argyle
Once vast cattle country, Lake Argyle now sprawls like an inland sea – Western Australia’s largest freshwater lake, created by the damming of the Ord River. Scattered with over 70 islands, its glassy waters teem with life, like freshwater crocodiles, barramundi, bony bream, sleepy cod and over 240 bird species. That’s nearly a third of Australia’s avian population.
Glide across the lake’s surface on a cruise as part of AAT Kings’ Untamed Kimberley tour, where the silence is only broken by the splash of fish and the call of birds. For Carolyn, this place is a perfect example of how WA’s landscapes surprise visitors. “Lake Argyle is a big puddle of water that became a game-changer,” she says. “Seeing it from a boat, coach, and plane is mind-blowing. It puts time, isolation and the sheer scale into perspective.”
