Tvindefossen waterfall is 12 km from Voss, usually said to be 152 metres high, but likely only 110 metres, is formed by a small stream, the Kroelvi, tumbling over a receding cliff. It is famous for its beauty. Buses sometimes stop for people to admire it. It was painted in 1830 by Johan Christian Dahl.

The water at Tvindefossen waterfall acquired a reputation for rejuvenation and revival of sexual potency that made it one of the most important natural tourist attractions in western Norway, with as many as 200,000 people a year from the U.S., Japan and Russia visiting and filling containers with the water. Beside the waterfall just outside Voss centre, set in lovely surroundings, you can find a campingsite.
