Trail Fast Facts
Boulder Creek walk is a 2km, grade 3 hike in Kakadu National Park, Northern Territory. This hike typically takes 1 hour to complete.
Hike Overview
The Yurmikmik Boulder Creek Walk is a perfect option for those seeking a shorter, scenic adventure in Kakadu National Park. This moderately challenging 2-kilometre loop trail is ideal for the wet season and typically takes around 1 hour to complete.
The walk begins near Plum Tree Creek, a seasonal waterway named after the billygoat plum (marlak) that grows along its banks. Look out for colourful birds flitting amongst the creek banks, such as the striated pardalote (pirn'pirntok) and the rainbow bee-eater (wirrirtwirrirt). As you progress, the open woodland gives way to a lush monsoon forest lining the path along Boulder Creek. Here, towering fan palms (karnpayn) stand sentinel amidst impressive sandstone and conglomerate boulders.
Take a moment to appreciate the contrasting textures and geological history – the smooth sandstone formed from ancient, slow-moving water, while the pebbly conglomerates were deposited by powerful floods millions of years ago. Keep your ears peeled for the call of the pheasant coucal (pukpuk) as you navigate the marked track over the boulders. The loop trail eventually returns you to the carpark, with the option to extend your walk by detouring to the Yurmikmik Lookout for even more spectacular views.
Remember, a park pass is required to enter Kakadu National Park. Consider purchasing yours online before your visit to save time upon arrival.
Nestled between the Marrawal Plateau and the South Alligator River lies Yurmikmik, a region named by the Jawoyn people. Hikers seeking to explore this area will find a network of trails particularly suited to the wet season. However, be cautious of sudden flash floods in the creeks during this time.
The walks offer a contrasting experience. As you traverse the paths, you'll transition from the cool embrace of monsoon forests and flowing creeks to the warmth of open woodlands. The vegetation also transforms, with towering trees in the valleys giving way to hardier, stunted plants on the rocky ridges and plateau.
All trails begin and end at the designated carpark. Shorter walks are clearly marked with either yellow-topped posts or orange arrows painted on rocks. If you choose a longer track, be aware that these are unmarked.
Camping: Permits are mandatory for camping in Yurmikmik. Camping is strictly prohibited near Motor Car Falls. To minimize environmental impact, bury toilet waste at least 15 centimetres deep and at least 100 metres from campsites and water sources. Wash well away from creeks and pools, and avoid using soap, shampoo, or detergent near water bodies as they can harm wildlife.
Important Safety Note: While Motor Car Creek is located upstream of known saltwater crocodile territory, these reptiles can still enter the area undetected during the wet season. Entering the water here is at your own risk. The South Alligator River, however, is confirmed saltwater crocodile habitat, and swimming there is strictly forbidden under any circumstances.
