Laos high annual rainfall, mountainous terrain and extensive river systems create some of the most impressive waterfalls in the world.
Laos’ Khone Phapheng Falls is the largest waterfall by volume in Southeast Asia.
Kuang Si Falls
Luang Prabang
The Kuang Si Falls, sometimes spelled Kuang Xi, is a three levelled waterfall about 29 kilometres (18 mi) south of Luang Prabang. These waterfalls are a favourite trip for tourists in Luang Prabang. The falls begin in shallow pools atop a steep hillside. These lead to the main fall with a 60 metres (200 ft) drop.
They are accessed via a trail to a left of the falls. The water flows in to a turquoise blue pool before continuing downstream and include many cascades.
The locals charge a nominal admission fee to visit the site, but it is well maintained with walkways and bridges to guide the visitor. Most of the pools are open for swimming.
Tad Yuang Falls
Champasak
Tad Yuang is impressive, with its twin torrents falling about 40 meters and flowing into lush jungle. It’s hugely popular with day-trippers from Pakse and Thailand who like to picnic at the top, so getting there early or lingering until dusk after the crowds have cleared out is a good idea. Swimming at the bottom is permitted
Tad Fane
Champasak
This natural tourism site is located within the Dong Houa Sao National Protected Area at Ban Lak 38 Village (Km 38) along Route 23 heading towards Paksong. The Champi and Pak Koot rivers flow off the plateau and come together here to create the Tad Fane Waterfall, which falls an impressive 120 metres.
The real beauty of this waterfall stems from its two branches of water, which divide as they spill over the steep cliffs. A seemingly endless flow of water is created and if windy, the mist sprays create spectacular rainbows.
Ziplining is available for the more adventurous.
Tad Sae
Luang Prabang
The Tat Sae Waterfalls are located along a tributary of the Nam Khan River in Luang Prabang Province. They are located about 18 kilometres (11 mi) southeast of Luang Prabang and about 2 kilometres (1.2 mi) from the village of Bak En. The falls flow over limestone formations amongst trees. Adventurers can zipline across the falls.
Khone Phapheng Falls
Champasak
The Khone Phapheng Falls is a series of cascading waterfalls located in Champasak Province on the Mekong River in southern Laos, near the border with Cambodia. They are the largest in southeast Asia and they are the main reason that the Mekong River is not fully navigable into China. The falls are characterised by thousands of islands and countless waterways, giving the area its name Si Phan Don or ‘The 4,000 islands’.
The highest falls reach to 21 metres (69 ft); the succession of rapids stretch 9.7 km (6.0 mi) of the river’s length. The average discharge of the cataract is nearly 11,000 m3/s (390,000 cu ft/s), with the highest flow on record at over 49,000 m3/s (1,700,000 cu ft/s).
The falls are home to the plabuck, an endangered species of catfish said to be the largest freshwater fish in the world. The plabuck is alleged to reach lengths of 3 m (10 ft) and weights of up to 646 pounds (293 kilograms).
