Eight miles (13km) from Sapa is the Thac Bac Water fall (the one in the picture). You can get here easily on a motorbike.
This is one of the region's major attractions. It is possible to climb to the top of the waterfalls. From there, there is an excellent view of the waterfalls.
If you come here, follow the road and you will get to the Tram Ton pass.
