Jim Jim and Twin Falls area to remain closed in 2026

Parks Australia advises that the Jim Jim and Twin Falls area will remain closed in 2026 while critical road and infrastructure upgrades are delivered. 

Kakadu has been impacted by cyclones resulting in substantial damage to roads in the area. 

Following engagement with Traditional Owners for the area and detailed site assessments, Traditional Owners expressed their concerns for the safety of visitors to their Country and have requested that the area remain closed until all road upgrade projects are completed. Parks Australia respects and supports this decision. 

The closure includes all sites in the area including Jim Jim Falls, Twin Falls gorge and escarpment walk, and Karnamarr campground. Road and infrastructure upgrade works are scheduled to commence in June 2026 and are expected to be completed by December 2026, ahead of the area reopening for the 2027 dry season. 

These projects include: 

• Jim Jim Falls Road: Upgrades for a 19.25 km section of Jim Jim Falls Road to gravel standard which will improve the safety and amenity of this roadway.  
• Secondary and tertiary road upgrades in the Jim Jim area include upgrades to several floodways and natural spring crossings along the 4WD tracks between Karnamarr Campground, Jim Jim Falls and Twin Falls (Jim Jim Falls 4WD track, and the Twin Falls 4WD track). 

Director of National Parks Ricky Archer said while the decision would be disappointing, it reflected a shared commitment to safety, responsible management of Country and delivering long-term improvements that support sustainable access into the future. 

“Kakadu National Park is jointly managed, and decisions about visitor access and infrastructure are made in partnership with Traditional Owners to ensure developments respect cultural values and protect the park’s unique natural and cultural heritage,” Mr Archer said. 

“Importantly, Kakadu remains open, and visitors can continue to experience many of the park’s iconic cultural and natural attractions while these essential works are completed.”
