The Northern Territory is not the kind of place most people associate with swimming. They picture red dust and spinifex, extreme heat and isolation, Uluru at sunset and crocodile warning signs. And while all of that is absolutely true, the NT also has some of the most beautiful natural swimming holes in Australia — fed by crystal-clear springs, hidden in gorges of red sandstone, and framed by ancient rock art and ghost gum trees.
Some of these swimming holes are famous and well-visited. Others require a short bush walk or a drive on an unsealed road to reach. All of them are extraordinary, and all of them offer the special pleasure of cooling off in fresh, clear water in the middle of the Australian outback — an experience that feels both surreal and deeply restorative.
Before we go anywhere near the water, though, let’s address the most important thing about swimming in the Northern Territory: crocodiles. Saltwater crocodiles are present in rivers, estuaries, and waterways across the Top End, and they are genuinely dangerous. Always, always check for crocodile warning signs. If there’s a sign, don’t go in. If there’s no sign but the water is murky, near mangroves, or close to a river system, err on the side of caution. The swimming holes in this guide are generally safe — but this is Australia’s far north, and you must always use your common sense.

💧 Bitter Springs, Mataranka — float through the thermal springs
Bitter Springs near Mataranka, about 420 kilometres south of Darwin, is one of the Northern Territory’s most beloved natural experiences — and one of the most unique swimming spots in all of Australia. Here, naturally warm spring water (a constant 34°C year-round) bubbles up from an underground aquifer and flows through a narrow, palm-lined channel before joining the Roper River. You collect a pool noodle, wade in at one end, and float gently downstream through cathedral-like stands of livistona palms for about 20 minutes, before walking back along a path through the palms and doing it again.
It sounds simple, and it is — but the experience is genuinely magical. The water is beautifully clear with a slight blue-green tint, the palms create a dappled canopy overhead, and small fish dart around your feet as you float. It’s the kind of place that encourages you to slow right down and do absolutely nothing, which in the heat of the outback is exactly what you want.
Bitter Springs is located in Elsey National Park, which also contains the original Bitter Springs thermal pool (accessed from a different entry point and offering a more enclosed, hotter experience) and the beautiful Roper River, where freshwater crocodiles (harmless to humans if unprovoked) are commonly seen. The area is also famous for its association with Jeannie Gunn’s classic Australian novel “We of the Never Never,” set on Elsey Station nearby.
🌊 Florence Falls, Litchfield National Park
Litchfield National Park, about 1.5 hours south of Darwin, is home to some of the Northern Territory’s most accessible and spectacular swimming holes, and Florence Falls is the crown jewel. Twin waterfalls drop from a sandstone escarpment into a large, deep plunge pool surrounded by monsoon rainforest. The water is clear, cool (around 25°C), and fed year-round by a reliable spring system that keeps the falls running even in the dry season.
Access to Florence Falls involves a descent of 135 steps down a well-maintained stairway to the plunge pool below. The pool is generous enough that it doesn’t feel overcrowded even on busy days, and the waterfall itself creates a natural shower that’s incredibly refreshing in the dry season heat. Bring a snorkel — the pool has excellent visibility and small fish dart around the boulders at the base of the falls.
There’s also a 4-kilometre return walk from the Florence Falls car park to the top of the falls and along the creek above, passing through beautiful savanna woodland and paperbark forest. The walk connects to the Buley Rockhole, a series of natural rock pools just upstream that are fantastic for a more casual wade. On weekends, the Buley Rockhole area can get quite busy — visit early in the morning for the most peaceful experience.

🏔️ Wangi Falls, Litchfield National Park
Wangi Falls (pronounced “Wong-eye”) is the most accessible and busiest swimming hole in Litchfield, and with good reason — it’s magnificent. A large, two-tiered waterfall cascades into a wide, deep plunge pool framed by fig trees, palms, and lush monsoon rainforest. The pool is large enough to accommodate significant numbers of swimmers without feeling crowded, and the surrounding forest provides shade and a dramatic natural backdrop.
Wangi has excellent facilities — shaded picnic areas, toilets, a kiosk with food and drinks, and a swimming enclosure within the pool that’s maintained to be crocodile-free during the dry season. The swimming area is closed during the wet season (roughly November to April) due to the risk of crocodiles being swept into the pool during floods — the NT Parks rangers take this seriously, so always check current conditions before visiting.
The 1.6-kilometre Wangi Falls circuit walk takes you up to the top of the falls and through monsoon forest, with interpretive signs explaining the ecology and Aboriginal cultural significance of the area. Freshwater crocodiles are common in the upper sections of the creek above the falls — they’re visible from the walking track and are generally harmless to humans unless provoked.
🌿 Edith Falls (Leliyn), Nitmiluk National Park
Edith Falls, known by its Jawoyn name Leliyn, is located near the town of Katherine and is the less-visited but arguably more beautiful alternative to the Litchfield swimming holes. The falls themselves are a series of cascades dropping down a sandstone escarpment into a large, clear plunge pool, and beyond the main pool, a trail leads up through the gorge to a series of upper pools with extraordinary views over the surrounding country.
The upper pool walk (2.6 kilometres return) is the highlight — a moderately challenging climb through spinifex and sandstone that delivers you to a tiered series of natural rock pools with sweeping views of the escarpment country. Pack a lunch, bring plenty of water, and spend the afternoon up there — it’s one of the most peaceful and beautiful places in the entire Northern Territory.
Edith Falls is open year-round for swimming in the main plunge pool. Freshwater crocodiles are present and commonly seen sunning themselves on rocks near the pool — they’re small and shy, and there are no recorded attacks on humans from freshwater crocodiles at this site. The falls are about 42 kilometres from Katherine, on the sealed Stuart Highway, making them very accessible as a half-day trip from town.
🦅 Gunlom (UDP Falls), Kakadu National Park
Gunlom is one of the most extraordinary swimming spots in Australia, and not enough people know about it. Located in the southern section of Kakadu National Park, about 170 kilometres south of Jabiru on a partly unsealed road (accessible to 2WDs in the dry season), Gunlom features a large plunge pool at the base of a waterfall and — the real draw — a series of natural infinity pools at the top of the escarpment with uninterrupted views over the Kakadu floodplains stretching to the horizon.
The walk to the top pools takes about 45 minutes from the car park — it’s steep in places and requires a reasonable level of fitness, but the reward at the top is extraordinary. The highest pool sits right at the edge of the escarpment, creating a natural infinity pool effect where the water appears to flow directly out into the vast wilderness below. Swimming here, watching black kites wheel overhead against a deep blue sky and the floodplains stretching away in every direction, is one of those genuinely transcendent travel moments.
Gunlom is also a significant cultural site for the Jawoyn traditional owners of this part of Kakadu. The waterfall is home to Bula, a Creation Ancestor of great power, and the area is treated with deep respect. Stay on marked trails, don’t touch or remove any rocks, and be particularly mindful around any rock art sites in the area.

🌊 Nitmiluk (Katherine) Gorge swimming
Katherine Gorge — known by its Jawoyn name Nitmiluk — is a spectacular series of 13 gorges carved through ancient sandstone by the Katherine River. While the gorge is most famous for its canoe and boat tours (which are genuinely spectacular), there are also excellent swimming opportunities throughout the gorge system. The first gorge has a swim beach accessible from the main visitor centre, and the rock pools accessible by canoe or on foot deeper in the gorge system are exceptional.
Freshwater crocodiles are present throughout Nitmiluk Gorge and are commonly seen on rock ledges. They’re harmless to humans in normal circumstances, but always follow ranger advice about specific swimming areas. Saltwater crocodiles can occasionally enter the lower gorge during the wet season, which is why the gorge tours and swimming areas close during the November to April wet season.
🌿 Sandy Creek, Douglas Hot Springs
Douglas Hot Springs, located about 110 kilometres south of Darwin on an unsealed road, offer a different and delightful kind of waterhole experience. Hot mineral springs (around 40-42°C) emerge from the ground and mix with cooler Sandy Creek water to create natural thermal bathing pools of varying temperatures. The springs are in a beautiful paperbark woodland setting and attract birds in large numbers — you’ll see brolgas, jabiru storks, and enormous flocks of corellas if you visit in the early morning.
Douglas Hot Springs is more of a soaking experience than a swimming hole — the spring pools are small and very hot — but it’s genuinely lovely and far less visited than the Litchfield sites. The adjoining Sandy Creek (below the spring confluence) is cooler and can be waded in dry season, and the birdlife along the creek banks is excellent. Access requires an unsealed road that can become impassable after heavy rain — check conditions before visiting.
📅 Best time to visit NT waterholes
The dry season (May to September) is by far the best time to visit Northern Territory waterholes. During this period, most swimming holes are open, water levels are stable and clear, crocodile management measures are in place, and the weather is warm but not brutally hot (temperatures of 25-32°C during the day). This is also when the waterfalls are at their most accessible — the cascades are still running from the wet season rains but are not in flood.
During the wet season (October to April), many swimming holes close due to flood risk and the increased chance of saltwater crocodiles being swept into normally safe pools. Some sites, like the Mataranka thermal springs, remain open and are actually particularly beautiful in the green season. If visiting in the wet season, research each individual site carefully and always follow the advice of NT Parks rangers.
💡 Safety tips for NT swimming holes
- Crocodile awareness is non-negotiable. Read all signage at every swimming hole before entering the water. If a site is closed, it’s closed for a good reason — don’t ignore the signs. Stick to designated swimming areas and never swim at dawn, dusk, or after dark when crocodile activity is highest.
- Water quality can vary. After heavy rain, some swimming holes become discoloured and carry higher pathogen loads. Use your judgement — if the water looks brown or murky, wait for it to clear or swim elsewhere.
- Sun protection is critical. The UV index in the NT is extreme. Wear SPF 50+ sunscreen, a hat, and UV-protective swimwear. You will burn faster than you think, especially when floating on your back in a thermal spring.
- Hydrate constantly. The combination of heat, physical activity, and swimming (which masks how much you’re sweating) can cause dehydration very quickly. Drink at least 500ml of water per hour when active in the NT heat.
- Tell someone your plans. If you’re visiting a remote swimming hole, let someone know where you’re going and when you expect to return. Mobile coverage is extremely limited or non-existent in most national park areas of the NT.
