Xayaboury - also named Xayabuli, Xaignabouli, Sayaboury and Sayabouli - is a northwestern province of Laos, home to some stunning natural sights and cultural attractions. The capital, also known as Xayaboury, lies on the western banks of the Mekong River and gives visitors the chance to view traditional steep-roofed wooden houses in the area of Pak Lay Town. A mountainous province, Sayaboury will delight outdoor enthusiasts with its selection of caves (such as Tam Hine and Tham Phaway), waterfalls (Tad Namyal, Tad Namphong and Tad Fanh) and hiking opportunities, while those looking for rich cultural experiences should check out the Tai Lue-style temples of Vat Ban Khon (known for their rare murals made of natural fibres) and the diamond-shaped stupa of Vat Si Phan Don.
