Darwin to Mary River
It’s croc country, birdwatching heaven and a patchwork of pristine wetlands that’ll have any nature lover grinning. Whether you’re after barra fishing, a Safari Cruise or cracking landscape shots, the drive from Darwin to Mary River is more than a transit leg. It’s the whole Top End experience in a couple of hours.
Most people leaving Darwin have one destination: Kakadu National Park. Fair enough, it’s a beauty. But if you bolt straight there, you’ll miss one of the best ecosystems in the Northern Territory — the Mary River National Park.
The Calm Before the Crocs
Start your journey in Darwin, grab supplies and fuel up. Once you hit the Arnhem Highway, the city disappears quickly and the floodplains and bush scrub take over. This one hour drive from Darwin feels like a portal into the wild.
First stop? Fogg Dam Conservation Reserve — a must-see for birdos. It’s a permanent wetland that stays lush even in the dry floodplain season. Great for spotting native birdlife and brushing up on croc safety (read those crocodile warning signs).
Next up, the Window on the Wetlands Visitor Centre. Check the park sites status here for road closures or weather alerts (especially in the Wet).

Corroboree Billabong
If you only have time for one stop, make it Corroboree Billabong. This permanent wetland is a magnet for migratory birds, exotic birds and yes — plenty of saltwater crocodiles.
Why it’s a Must-Do:
- The highest concentration of saltwater crocodiles per km on earth.
- Loads of bird species: pygmy geese to white-bellied sea eagles.
- Accessible via sealed road, just an hour’s drive from Darwin.
- Stunning scenic cruises: glide past lilies and lurking crocs on a 2.5-hour wetland cruise.
Whether you’re after a Mary River Wetlands Cruise, an airboat safari or just a boat cruise, Corroboree Billabong has got you covered.
Local Tip: The air cruise vessel gives you a bird’s eye view of the endless floodplains. For landlubbers the 2.5 hour cruise is pure magic.
Barra Fishing & Croc Watching Central
Further down the track is Shady Camp, famous for hooking the big one – barramundi.
But it’s not just about the fish:
- Croc spotting from the causeway (freshies and salties share this turf).
- Access to the wetlands, home to loads of bird life.
- Basic camping facilities in the parks – but watch out for croc warning signs.
Access Note: Rockhole Road is a gravel road suitable for 2WD in the dry but you’ll want a high clearance vehicle if there’s been rain.
Couzens Lookout: For Those NT Views
This must-see park is more than just crocs and birds (though they’re the stars). It’s a living, breathing game reserve of diverse habitats:
- Dry floodplain grasslands.
- Pristine wetlands and water reserves.
- Paperbark forests are full of native birdlife.
The Territory Wildlife Park nearby has interactive displays if you want to learn before you head bush.
*Park Safety Signs: Always follow them. This is active croc country, not a petting zoo. Check park sites status updates. Seasonal rains can change accessibility from “easy drive” to “bring a snorkel” in days. Check Park sites StatusCommentsForecast before you head out.
Birdos: Not Just for the Twitchers
If you have even a passing interest in birds Mary River will blow your mind. From Bird Billabong to the back reaches of Corroboree you’ll see:
- Loads of birds — kingfishers, herons, magpie geese.
- Bird hides for unobtrusive viewing.
- Interactive bird guides at the Visitor Centres.
- Regular sightings of Mary River specials.
Peak birding is the early dry season when the migratory birds arrive in droves.
Accommodation & Camping
Options range from rough to comfy:
- Mary River Wilderness Retreat: lodge rooms and safari tents.
- Corroboree Park Tavern: pub vibes with rooms.
- Shady Camp: low-cost camp bush sites.
- Houseboat holiday: Yep, you can drift the billabongs in style.
For those after a bit of luxury, there are luxury accommodations and luxury accommodation options closer to Darwin. But honestly, a swag under the stars feels more right out here.
Experienced guides
The scenery on a Mary River cruise is great, but the guides do their best to add to the experience. They know the Billabong like no one else and will take you to the best spots depending on the time of day.
They know the area’s history, whether a storm has knocked down a tree or whether there are chicks in the nest, and can tell you about their favourite crocodiles.
They also do their best to make sure everyone can see everything interesting here. No matter which side of the boat you are on, both sides will be oriented so you can take great photos or see something special.
If you’re heading to Darwin on holiday, put the Billabong Corroboree Cruise to Mary River National Park on your bucket list.
Essential Trip Checklist
- Full tank of fuel (Humpty Doo or Coolalinga servo)
- Plenty of drinking water (3–5L per person, it gets dry as guts)
- Croc safety awareness — no swimming unless signed safe
- Decent mozzie repellent (they’re relentless in the wetlands)
- Binoculars for birdwatching
- Fishing gear if you’re after barra
- NT Parks Pass (required for Mary River NP access)
- Offline maps — don’t trust the mobile signal once you pass Humpty Doo
Crocodile Safety
Mary River’s crocs are no joke. Be croc-wise:
- Respect crocodile safety zones.
- Heed crocodile warning signs — they’re there for a reason.
- Don’t wade, paddle or get cheeky near the edge.
- Keep an eye out for big crocs known to locals.
- Freshwater crocodiles (freshies) are generally shy, but salties? Different story.
Croc Count: Corroboree Billabong and Shady Camp have the highest concentration of these ancient monsters. Always assume they’re watching.
