Located about 13km's down a winding alpine road from Sa Pa town, the majestic Silver Waterfall thunders 200 metres down the cliffs of the Hoàng Liên Son Mountains from the headwaters of the Lo Sui Tong peak. Known to locals as "Thác Bạc" the falls are fed by glacial runoff that originate near the summit of Fansipan, the highest peak and "Roof of Indochina"
