Through the Dark: Exploring Tunnel Creek’s Underground River
A cool subterranean shortcut through the Kimberley—history, geology and a walk in an underground river
You duck beneath a low arch of honey-coloured limestone and the light behind you shrinks to a coin. The air cools, humid breath from the earth pooling in the tunnel mouth. Ahead, the underground creek—clear as glass, waist-deep in places—threads through the cave like a dare. Your headlamp beam picks out water-smoothed walls, fossilized ripples, and the occasional white flash of a ghost bat spiraling along the ceiling. This is Tunnel Creek: a living corridor chiseled by time and water, an ancient subterranean shortcut through the rugged limestone of the West Kimberley.
Trail Wisdom
Bring a reliable headlamp
The tunnel is dark and headlamps (plus a spare) free your hands for balance and photo composition.
Wear water-friendly footwear
Soles with good grip or neoprene boots reduce slips on algae-smoothed rock and protect feet from sharp stones.
Check seasonal access
Wet-season storms can flood the cave and wash out roads—confirm local conditions or join a guided tour.
Respect cultural sites
Tunnel Creek is significant to the Bunuba people—ask for local-guided options and avoid disturbing marked features.
Local Knowledge
Hidden Gems
- •Windjana Gorge’s riverside walks—great for spotting freshwater crocodiles from a safe distance
- •A nearby cave entrance with fossilized ripple marks—visible on the cave walls if you look closely
Wildlife
Ghost bats, Freshwater crocodiles
Conservation Note
The cave hosts sensitive bat colonies and fragile limestone formations—stick to paths, avoid touching formations and pack out all waste.
Tunnel Creek was used as a hideout by Bunuba leader Jandamarra in the late 19th century, tying the site to important Indigenous resistance history.
Seasonal Guide
spring
Best for: Wildflowers on escarpments, Lower creeks and wildlife spotting, Quieter tours
Challenges: Occasional late-season rains, Warmer days and cooler nights
Spring edges toward the dry season—flowers and wildlife are active but check for residual wet patches after summer storms.
summer
Best for: Lush landscapes after storms, Fewer crowds (with access caveats), Dramatic stormscapes
Challenges: Monsoonal rain, closed roads and flooding, High heat and humidity
Summer (wet season) brings dramatic weather and rich vegetation but often closes access; many tours operate only in the dry months.
fall
Best for: Clear skies and comfortable temps, Excellent visibility for helicopter flights, Peak dry-season access
Challenges: Cooler nights and busy tourism windows
Autumn moves fully into the dry season—perfect for combining Tunnel Creek with aerial or overland trips as roads firm up.
winter
Best for: Ideal visiting conditions, Calm, cool water in caves, Peak wildlife visibility
Challenges: Higher demand for tours and accommodation, Chilly morning starts
Winter (May–August) is the optimal season—dry, mild days and reliable access make it the busiest time to visit.
Photographer's Notes
What to Bring
Headlamp (plus spare batteries)Essential
Hands-free light is essential for navigating dark passages and for photography.
Water shoes or neoprene bootsEssential
Protects feet and improves grip on slippery, uneven cave floors.
Light, quick-dry layers and a dry bagEssential
You’ll get wet in the cave—dry layers afterwards are important for comfort and warmth.
Small first-aid kit and insect repellent
Useful for minor cuts, scrapes and for dealing with insects in warmer months.
Common Questions
How long is the walk through Tunnel Creek?
The cave passage is roughly 700–800 metres; expect a round-trip visit to take 45–90 minutes depending on water levels and group pace.
Do I need a guide to visit Tunnel Creek?
You can visit independently, but guided tours add cultural interpretation, transport from Broome and up-to-date safety info—recommended if you’re unfamiliar with the area.
Is it safe to wade the creek?
Generally yes if water levels are low; wear good footwear, watch for uneven rock and avoid deep pools if crocodile signage is present.
When is the best time of year to go?
The dry season (May–September) offers the most reliable access; winter months are ideal for weather and road conditions.
Are there bats or wildlife in the cave?
Yes—several bat species roost in the tunnel, and you may see freshwater fauna; keep noise low and don’t disturb roosts.
Can Tunnel Creek be combined with other Kimberley highlights?
Absolutely—many multi-day tours link Tunnel Creek with Windjana Gorge, Bell Gorge, Horizontal Falls and helicopter excursions for a broader Kimberley experience.
What to Pack
Headlamp (navigation), water shoes (foothold), dry layers (warmth after the walk), water bottle (hydration)
Did You Know
Tunnel Creek served as a hideout for Bunuba warrior Jandamarra in the late 1800s during his resistance against colonial forces.
Quick Travel Tips
1) Book tours in the dry season; 2) Carry spare batteries for lights; 3) Respect cultural signage and guided options; 4) Combine Tunnel Creek with Windjana Gorge for a full-day geology loop
Local Flavor
Broome’s pearling legacy and Bunuba culture shape regional cuisine and story—pair a Tunnel Creek visit with a pearl farm tour or a seafood meal in Broome to taste local flavor.
Logistics Snapshot

Sustainability Note
Support operators that engage Bunuba guides and practice low-impact visits; avoid disturbing bat roosts and never leave waste in the cave.
