Access Guide to the 2026 Road Closures of Kakadu National Park
If you have put Jim Jim Falls or Twin Falls on your itinerary for 2026, the road closures in Kakadu National Park could put a different spin on your trip. The sensible thing to do is consult the Road Report NT and the most recent Kakadu Access Report prior to your departure; what appears to be an open road on a map can be shut down by a cyclone, rain, flooding or some infrastructure work.
I am Riley Pearson. When I put together travel plans I do as I would with client aftercare: read the instructions, see what the conditions are and not put stock in a warning sign for its drama value. This guide will cover the current state of affairs as per the 2026 update, from 4WD access and the Jim Jim and Twin Falls closures to wet-season rules and other sites worth visiting.

The 2026 Situation in Kakadu
Restricted access to Jim Jim Falls and Twin Falls is the main concern for planners this year, that includes parts of Jim Jim Road and the gorge at Twin Falls. Upgrades to the infrastructure and damage from hard weather are given as the cause; for anyone planning a visit to this remote Arnhem Land escarpment falls destination, when they might open again is a matter of safety and conditions.
Then there is the scale of it. At 20,000 square kilometres one can say “Kakadu is open” and still find a track, lookout or campground is not. There may be visitor sites open for business while a major road is not. You will appreciate the difference when you are several hours into a drive with your camping equipment and esky in tow.
What we know from the update
According to the 2026 data provided here, expect restrictions on the routes to and around Jim Jim Falls, Twin Falls and the Gorge. As there is no complete register of closure dates to go by, or a sure-fire reopening date for all sites, consider any opening date put forward as provisional.
Before you head out, make use of the Parks Australia information for Kakadu as well as the NT reports. Have another look in the morning of your travel. In the Top End a serious bout of weather can turn a place that was “recently open” into “not today, mate”.
Visitor Sites and Closed Roads
For a trip centred on the waterfalls the key closures are at Jim Jim and Twin Falls. The unsealed roads, creek crossings and walking conditions can be made unsafe in short order, so the park will close them even if the highway is fine. Do not make your plans on one attraction without the connected route in mind. A restriction at Twin Falls Gorge has implications for the walk, the shuttle or camping, and a closed Jim Jim Road is more than just the end of the tarmac.
2026 Waterfall Access
Jim Jim and Twin Falls are the ones making headlines in the current update. But do not assume Karnamarr campground, the Barrk Marlam walk or Bilkbilkmi (Graveside Gorge) are in the same boat as the falls; check them on their own merits.
And pay attention to how a closure is worded. “Site closed” leaves the road open but the swimming area or track off limits. “Road closed” is self explanatory. “Access subject to conditions” means it might be open now and not later in the day.
Make proper use of the closure map
It will tell you which roads lead where but is no replacement for an up to the minute alert. A map is good for geography but will not inform you of a culvert that has been damaged, a causeway under water or a temporary measure put in place that morning.
Put your intended return route and fuel stops on paper and an alternative site. Save the alerts while you have reception. And if a ranger or a sign tells you to stay off a road, do so. Having a 4WD does not make a closed road optional.
The case of Jim Jim and Twin Falls
You will find the 2026 closures are due to both weather and the need for some infrastructure work. Heavy machinery and unfinished drainage are not risks to be taken with ordinary traffic so a full closure is called for.
Add in some cyclone damage and it is not so neat and tidy. There is a flatness to the surface of a road in Kakadu that can be deceiving; water will work its way under it. And when the skies have put their clouds away, an approach washed out by rain or a tree down on the track is still a hazard. The road has to be more than something for a hardy individual to get by on, it must be secure for maintenance and emergency crews.
Provisional Opening Dates
One should not take a target opening date as given. It is contingent on a host of things: how the repairs and inspections go, the state of the creeks after a rainfall, contractor access and what testing reveals about the road’s stability. Take “weather permitting” at face value, in the changeover from wet to dry season at any rate.
Make no plans to put down money on a non-refundable activity tied to a target date without the operator vouching the site is open. Put in a call to see if you can be put in at Ubirr, Nourlangie, Yellow Water or somewhere else within reach. It is a minor enquiry but one that will spare you a long drive and an afternoon of ill humour.
Sites to Put at the Top of the List
The question of what is open in the park does not have a single answer, so consider it on a site by site basis. There are operational differences and variations in the terrain and water levels at Maguk, Gunlom Falls, Cahills Crossing, Yellow Water, Nourlangie and Ubirr.
Consult the most recent visitor alerts for Kakadu National Park since availability is fluid. A closed waterfall is no reason for a poor outing; opt for some rock art or a walk of a length suited to the day, or spend time with the wildlife in the wetlands.
How to Plan for the Day
For a single day it is better to make of one region than to attempt to tick off the entire park. From your point of departure and the roads as they are, Nourlangie and Yellow Water might make a sensible day in the west or centre, whereas a run east to Ubirr and Cahills Crossing is equally doable.
Factor in the heat, slow moving traffic, a need for the toilet or to put the camera to use. You could be put behind schedule by a road train or some wildlife taking its time to cross. Then there is the matter of not having to come back over an unknown bush road in the dark to end a hot day; the locals have right of way and your plans are of no consequence to them.
A Quick Comparison
Consider this table a guide in your planning, not an opening register. If the site is not open, so much for the itinerary or social media photo.
Conditions to Check Before You Go
An access report is only as good as the time of checking. Have a look at Parks Australia and Road Report NT for the wider picture in the Territory, then measure it against the forecast and what your vehicle is up to. Do it once more on leaving your accommodation or Jabiru; reception is not to be relied on and there is nowhere to turn around on some of these roads once things have gone bad. With children or anyone with less mobility in tow, be sure on the walking surfaces and the like.
Pre-Trip Checklist
- Run through the Kakadu Access Report and the visitor alerts.
- See what Road Report NT has to say on closures and flood warnings.
- Jim Jim and Twin Falls, Karnamarr and the walks you have in mind should be confirmed in their own right.
- For Cahills Crossing in particular, check the tides and daylight.
- Have your offline directions, a spare tyre, provisions and sun protection with you.
- Let someone know where you are headed and when to expect you back.
As for costs, there is no price list to hand in the update. Verify what you are paying for in the way of fuel, camping, tours and passes. Set aside some AUD for a replacement activity or an extra night; remote travel has a way of making you pay for optimism.
Wet Season And 4WD Planning
One does not have to take the wet season road closures in Kakadu as a personal affront; they are simply part of normal operations. Then there is the matter of heavy rain putting an end to any unsealed roads or low-lying tracks and crossings, and the humidity which will make a walk more arduous and put the brakes on your recovery from the least bit of exertion.
While you can count on the dry season for a degree of predictability, “dry” is no guarantee that all tracks are open. Storm damage, bushfires, local hazards and the odd repair job will still be in evidence. A 4WD gives better clearance and traction but it is not going to get you safely over deep water, around a barrier or shield you from a crocodile.
Know Your Vehicle Limits
A word to the wise before heading down a remote track: look at the condition of your tyres and spare-wheel setup, check your recovery points and clearance. Take on more water than what is required for the driving time alone in case of delays. And if corrugations, sand or shallow crossings are unfamiliar, there is safety in a tour rather than trying to learn next to a closed gorge.
Stick to low speeds on the corrugations and give other vehicles their space. Make no attempt to cross water where you cannot tell the depth or what is underfoot. An unapproved waterway is not for swimming; in crocodile country a pool’s quietness is no indication it is empty.
Who Should Forgo The Remote Tracks
The likes of Jim Jim and Twin Falls are not for those with limited walking ability, no recovery equipment or who would be at a loss making decisions on their own, nor for anyone requiring sealed-road access. They are also ill advised if the rain is on its way or the wording of an alert is ambiguous.
For beginners and families there are shorter walks, guided options and sites you can be sure are open. Plan a trip that allows for a change of mind without the day being spent in a makeshift bush mechanics workshop.
2026 Alternatives
Should the big falls be off limits, do not write off Kakadu, just put your attention elsewhere. There are the cultural and landscape offerings of Ubirr and Nourlangie, the wetlands and wildlife at Yellow Water, or a vantage point at Cahills Crossing to see the tides at close range.
You might consider Maguk or Gunlom Falls as an option, but only when the alerts for them say so. Do not be under the impression that one open waterfall means every route up the Arnhem Land escarpment is available. Every track has its own set of conditions.
Reality Check
It is easy to think a 4WD will put you at every well known spot in Kakadu. In fact, rough access roads call for safe water levels and sound culverts and bridges, and closures are enforced on all vehicles. Or you may believe the dry season is a clear run. It is more predictable but does not nullify cyclone damage, fires or site restrictions. You might plan to see it all in a day but the heat, the distances and the size of Kakadu will tell you otherwise. Pick a region and be gone before the light goes.
Some FAQs on 2026 Closures
Travellers are often caught out by these when putting together plans for the park. The answers here are straightforward but an official alert will always supersede a guide book.
What is closed in Kakadu National Park?
Our 2026 update puts restrictions on Jim Jim and Twin Falls and the approaches to Twin Falls Gorge due to infrastructure work and cyclone damage. But for the full story on any changes to campgrounds or walks, consult the visitor alerts.
Jim Jim Falls?
Access and the state of the infrastructure are the reasons for the 2026 closure, weather damage included. Parks Australia has to issue an opening notice before you should consider the target date confirmed.
And Twin Falls?
The 2026 closure has to do with getting the road and safety conditions right in and around the gorge. With the terrain and water hazards involved, you cannot expect a reopening once an obstacle is moved.
Is it possible to drive through?
Provided your vehicle is up to it and the roads are open, yes. But do not presume everything is sealed or passable in the wet season and never go where it is closed. Have a good look at the route first.
Is the Cahills Crossing road sealed?
Do not make of it an ordinary all-weather drive. Tides, water levels and wildlife are factors. Heed the barriers and the instructions in the access report. There is no need to wade in to see for yourself.
Be Flexible
An adaptable itinerary is the best policy for dealing with the 2026 road closures. Put some supplies aside for delays and have Ubirr or Yellow Water in reserve as you confirm the status of Jim Jim and Twin Falls and review the NT Road Report.
Kakadu will reward those who are attentive. Let the alert be the final arbiter and stay off a closed road. To have to alter plans is a minor irritation; a rescue that could have been avoided is something else entirely.
