Nam Ou River Trips: Nong Khiaw, Muang Ngoi and the Dams
Contents
The Nam Ou winds through limestone country in northern Laos, and the classic way to see it is from a long wooden boat. The best-known day out starts in Nong Khiaw: Asian Trails runs a round trip upstream to Muang Ngoi and back, stopping at ethnic-minority villages where weaving of silk and cotton textiles is on show, with lunch in Muang Ngoi and a short walk through rice fields to a cave that villagers used as a shelter during Indochina War bombing raids.[1] The day lasts 8 hours and departs at 08:30; times and stops are approximate and can change with weather and conditions.[1] You are back in Nong Khiaw in time for the sunset.
Choose the river section before you book
Muang Ngoi Kao is a quiet village on the banks of the Nam Ou, ringed by high karst mountains and sheer limestone cliffs.[2] Nong Khiaw is the natural starting point for the excursion above, and Muang Ngoi is the river destination if you want to stay beyond a day trip.
The river is also a working hydropower basin. The Nam Ou cascade has seven dams with a combined capacity of 1.27 GW; the first phase (Nam Ou 2, 5 and 6) has been fully operating since October 2016 and the second phase (Nam Ou 1, 3, 4 and 7) since September 2021.[3] POWERCHINA, the developer, says all units started generating electricity on 21 September 2021,[4] and that the stations entered commercial operation on 1 October 2021.[5] Because of the dams, ask your boat operator which stretch you will actually sail, where you board and whether you change boats or walk around a dam.
