Thac Bac lies beside National Highway No 4D, about 12km from Sa Pa Town’s centre. Silver Waterfall is formed by sources of water from the Lo Sui Tong mountain peak. From the distance, the waterfall looks like a white dragon looking down from the sky. You can reach the Silver Waterfall by motor bike or by car in half an hour. From there you can see stunning view of the surrounding mountains and the last forests belonging to Hoang Lien National Park.
