Houayxay (Lao: ຫ້ວຍຊາຍ, pronounced[hȕajsáːj]) (also Huoeisay, Huai Sai, Houei Sai or Huay Xai), is a district in Bokeo Province, Laos, on the border with Thailand. Ban Houayxay is the administrative centre of the district.
The town is the starting point for many boats (speed and slow boats, freighters, luxury cruisers for tourists and others) on the Mekong River to Pakbeng, Luang Prabang and other destinations.[2]
Houayxay is also home to the Gibbon Experience,[3] another highlight for tourists. It is a series of ziplines and treehouses providing a unique overnight experience.[4]
Fort Carnot, an ancient French fort in ruins, sits on a hill overlooking the town and the Mekong River.
