Nam Theun 2 Reservoir, Laos: Best Things to Do – Top Picks

Did you know that the Nam Theun 2 Reservoir in Laos isn’t just a stunning natural attraction but also powers over 75% of Thailand’s electricity imports from Laos? This 450 km² (174 mi²) body of water, created in 2008, represents an extraordinary blend of human engineering and natural beauty that has transformed into an emerging ecotourism destination. Nestled between the Nakai Plateau and the majestic Annamite Mountains, this vast reservoir offers visitors a rare glimpse into rural Laos while providing opportunities for wildlife watching, cultural immersion, and water-based adventures.

Overview of Nam Theun 2 Reservoir

Located in the central region of Laos, spanning the Bolikhamsai and Khammouane Provinces, this massive reservoir has become both an important energy source and an emerging destination for travelers seeking authentic experiences off the beaten path.

The reservoir’s creation involved the resettlement of local communities, who now live in villages along its shores. These communities have adapted their traditional fishing practices to the reservoir environment, creating a unique cultural landscape where visitors can witness the harmonious relationship between people and nature.

Surrounded by the protected Nakai-Nam Theun National Park, the reservoir area is home to remarkable biodiversity, including rare bird species, various fish populations, and occasionally glimpsed wildlife like Asian elephants that roam the surrounding forests.
