Top 10 Waterfalls in Laos
Laos is a country of rivers. The Mekong and its highland tributaries drain the Annamite mountains, the Bolaven Plateau, and the Luang Prabang highlands, producing waterfalls that range from swimmable travertine terraces to the largest waterfall by volume in Southeast Asia. The country's limited road network means that many falls require planning but rewards visitors who put in the effort. All are on the map.
1. Kuang Si Falls, Luang Prabang Province
Kuang Si (Tat Kuang Si) is the most visited waterfall in Laos, 29 kilometres south of Luang Prabang. A main fall drops approximately 60 metres in a multi-tiered cascade, feeding a series of turquoise travertine pools below that are designated swimming areas. The colour comes from calcium carbonate in the limestone-filtered water. A walking trail beside the falls continues to the upper rim and a 15-metre viewpoint. Best flow: July to November (wet season), though the pools maintain colour and swimmability year-round. Type: tiered plunge.
2. Tat Sae Falls, Luang Prabang Province
Tat Sae, 15 kilometres southeast of Luang Prabang, is a broad multi-tiered cascade on the Nam Khan River — wide, shallow, and turquoise. Unlike the enclosed pool character of Kuang Si, Tat Sae spreads across a wide rock shelf with multiple small falls side by side. Access in the wet season is by longtail boat from Ban Aen village. Swimming is permitted at the lower tiers. Best flow: September to November. Type: tiered cataract.
3. Tat Lo Falls, Salavan Province
Tat Lo on the Xe Set River on the eastern edge of the Bolaven Plateau is a two-stage falls within the Tat Lo village tourist area. The lower falls (Tat Lo itself) drop about 10 metres; the upper falls (Tat Hang) drop a further 12 metres. The area is a base for exploring the plateau's coffee plantations, minority villages, and secondary waterfalls on foot or by motorbike. Best flow: September to November. Type: cascade.
4. Tat Yueang Falls, Champasak Province
Tat Yueang on the Bolaven Plateau in Champasak Province is a 120-metre plunge from the plateau edge into a deep jungle canyon — one of Laos's most dramatic single-drop falls. The spray creates a permanent mist cloud visible from the road above. Access requires a rough 15-minute trail from the car park to the rim overlook; a longer descent to the base is possible in dry season. Best flow: August to November. Type: plunge.
5. Tat Champee, Champasak Province
Tat Champee (also Tat Champi) is a wide cataract on the Huai Yang river, north of Pakxe on the Bolaven Plateau, approximately 15 metres tall and 50 metres wide at flood. The falls are set in agricultural landscape with coffee and cardamom farms visible on the approach. Less visited than the plateau's major falls. Best flow: September to October. Type: cataract.
6. Tat Soung, Champasak Province
Tat Soung near Tad Fane Resort is reputedly the highest waterfall in Laos, dropping approximately 200 metres in two stages from the Bolaven Plateau rim into a forested canyon. Views are from the plateau edge; the canyon below is inaccessible without ropes. Best viewed from October to December, after the monsoon peaks, when flow is strong but visibility is clear. Type: tiered plunge.
7. Tat Fane, Champasak Province
Tat Fane (Tad Fane) near the Tad Fane Resort above Pakxong drops 120 metres in twin parallel plunges into a canyon on the Huai Yang tributary. A zipline above the canyon allows visitors to cross between the two plumes. The falls are on the Bolaven Plateau edge and accessible from the resort on a short trail. Best flow: August to December. Type: twin plunge.
8. Tat Kuangmai, Luang Namtha Province
Tat Kuangmai in the northern highlands of Luang Namtha Province is a remote multi-tier waterfall on a Nam Tha tributary, accessible as a day hike from Luang Namtha with a local guide. The surrounding forest is montane broadleaf and part of the Nam Ha National Protected Area. Best flow: July to October. Type: tiered cascade. 4-hour guided hike from Luang Namtha.
9. Pha Mok Falls, Vientiane Province
Pha Mok Falls near the town of Vang Vieng on the Nam Song River is a small but beautifully framed waterfall accessible as a half-day trip from Vang Vieng by tuk-tuk and short walk. The falls drop about 15 metres over karst limestone into a pool. Less visited than the tube floating and other Vang Vieng activities; worth including for the karst setting. Best flow: September to November. Type: plunge.
10. Khone Phapheng Falls, Champasak Province
Khone Phapheng Falls on the Mekong River near Si Phan Don (Four Thousand Islands) in southern Laos is the largest waterfall in Southeast Asia by volume and sometimes called the "Niagara of the East." The falls are not tall — the main drop is roughly 21 metres — but at monsoon peak the combined discharge across multiple channels exceeds 11,000 cubic metres per second. The geography is a series of rocky islands and channels spread across 10 kilometres of river width; the main falls viewing platform is at Don Khone Island, accessible by boat from Ban Nakasang. Best flow: July to November. Type: cataract.
Planning a Laos waterfall trip
Luang Prabang is the practical base for northern Laos (Kuang Si, Tat Sae); Pakxe for the Bolaven Plateau cluster (Tat Lo, Tat Yueang, Tat Soung, Tat Fane); and Si Phan Don for Khone Phapheng. The monsoon season (June to November) produces the best flow at almost all Lao falls, with October being the peak for flow-to-access balance. Bolaven Plateau roads become difficult in heavy rain; a motorbike or 4WD gives more flexibility than a car.
Kuang Si in detail
Kuang Si requires a tuk-tuk or hired vehicle from Luang Prabang (about 45 minutes each way). The entrance fee is modest by international standards and includes access to the bear rescue centre at the park entrance, which houses Asiatic black bears confiscated from the illegal wildlife trade. The lower turquoise pools are roped off into designated swimming areas; entry to the upper falls area above the main plunge is not permitted. Morning visits before 09:00 offer significantly fewer crowds. The falls flow year-round from a limestone-filtered catchment in the hills above, but pool colour and clarity are best from November to May (dry season) when suspended sediment is minimal. Wet-season visits from June to October produce more dramatic waterfall flow but cloudier pool water.
The Bolaven Plateau circuit
The Bolaven Plateau above Pakxe sits at around 1,300 metres elevation, which means it is significantly cooler than the lowland Mekong towns and captures orographic rainfall from moisture-laden winds coming off the Gulf of Tonkin. The plateau supports coffee, tea, and cardamom cultivation alongside its waterfall landscape. A motorbike loop from Pakxe via Pakse-Tad Fane-Tad Yuang-Tad Lo and back to Pakxe takes two to three days and passes all of the plateau's major falls. Road quality on the plateau is mixed; sections off the main highway require a motorbike or 4WD. All Lao falls are on the map.
