The middle section, known as the “Middle Noce,” offers Class IV rapids and starts from the town of Dimaro. The lower section, known as the “Lower Noce,” offers Class V rapids and starts from the town of Mostizzolo.

The North Johnstone River in Australia, located 20 minutes from Cairns, is a natural flow river and a popular destination for whitewater enthusiasts seeking a challenging adventure. Here, paddlers can expect Class IV to V rapids that present a difficult skill and endurance test. The river’s powerful hydraulics, drops, and jagged rocky outcrops demand skill and a deep understanding of the river’s nuances. Paddlers must be aware of the river’s ever-changing conditions, which can be affected by rainfall and other environmental factors, making it imperative that they’ve educated themselves well on what to bring on a whitewater rapid trip, especially in the case of an emergency.
Access to the North Johnstone River is limited, as it can only be reached by helicopter. Once paddlers arrive, they can expect to face difficult waters that require agility and experience during their four- to six-day adventure paddling, if they plan to start at the top. Paddling the North Johnstone River, which is the longest river in Australia, requires not only physical endurance but also mental fortitude.
You can experience narrow gorges with Class V whitewater rapids, as found in the Mordor section, where paddlers must be prepared for the unexpected and be able to make split-second decisions in dangerous situations. However, it’s not just the whitewater rapids that make Johnstone River dangerous. While rafting, you may also confront water dragons, crocodiles, eagles, spiders, and pythons.
White Nile, Uganda

Located in the Jinja region of Uganda, the White Nile is a legendary river renowned for its exhilarating whitewater rafting experiences. Adrenaline junkies flock to the region to test their limits against the wild rapids, towering waves, and rocky obstacles that make up this spectacular river. The Itanda Falls and Bujagali Gorge rapids are particularly famous for providing an adrenaline-pumping ride that is not for the faint of heart. You can choose to take on the Big Four rapids, including daunting Class V rapids, or opt for a calmer route. However, regardless of your choice, every decision and maneuver must be executed with precision, making this a test of both courage and expertise.
Although the construction of the Bujagali and Isimba dams has destroyed some Class V rapids like Namizi, The Bad Place, and Kyabirwa, the river still offers world-class whitewater rafting. The deep waters of the Nile mean that there are fewer large rocks, so while this may increase the likelihood of flipping and add anxiety to inexperienced paddlers, you’ll also be less likely to hit rocks when flipping. The rapids offer an incredible challenge that is not for the faint of heart. However, the river offers expert guides who follow proper safety measures, making the White Nile a formidable yet conquerable whitewater rafting destination for less experienced paddlers.

Known for its rugged rapids, untamed beauty, and turbulent waters, the river is considered one of the most dangerous in Asia for rafting. With Class IV to V rapids, like God’s House and Juicer, the river can test the mettle of even the most experienced adventurers. As such, paddling the river during high-volume periods such as September is a serious undertaking that experienced paddlers should only attempt.
Navigating the rapids of the Karnali requires not only technical skill but also a true sense of adventure and an unwavering determination to conquer nature’s challenges. Each rapid presents a new obstacle to overcome, demanding courage and resilience from every paddler.
