Trail Fast Facts
Jarrangbarnmi Walk is a 4km, grade 4 hike in Kakadu National Park, Northern Territory. The walk typically takes 2 hours to complete.
Hike Overview
The Jarrangbarnmi Walk, also known as the Koolpin Gorge Walk, offers an unforgettable Kakadu experience. This 4-kilometre return trail (Grade 4) winds through a stunning gorge in the park's southern region. The walk typically takes around 2 hours to complete.
Hikers can choose between a short amble to the captivating plunge pools and waterfalls at the gorge's entrance or venture further upstream (approximately 2 kilometres) for a more immersive experience. A bushwalking permit is not required for the shorter section, making it accessible to a wider range of visitors.
Jarrangbarnmi is a place of both rugged beauty and ecological significance. Lush greenery climbs the towering cliffs, creating a dramatic backdrop for your exploration. The gorge is also home to rare species such as the hooded parrot, which nests in termite mounds, and the vibrantly coloured Gouldian finch. Keep your eyes peeled for the barrk, or black wallaroo, as well.
It's important to remember that saltwater crocodiles inhabit the creek near the campground and vegetation pool. Swimming and collecting water in these areas is strictly prohibited. Always adhere to signage and permit conditions to ensure your safety and the health of the environment.
Jarrangbarnmi holds cultural significance for the Jawoyn people, with its name reflecting their creation stories. "Jarrang" translates to "flood" or "big water flow," while "barn" means "rift" or "gap." Camping beside Koolpin Creek is permitted, but requires a permit obtained well in advance due to the area's popularity.
