A crystal clear river is so clean that the 50ft deep riverbed can be seen from a bridge crossing over the water.
The 30km long Verzasca River in Switzerland is renowned all over the world for its clear turquoise waters.
But while pictures of the sparkling waters are often taken from the mountains surrounding the river or from bridges crossing over it, it’s much rarer to see photographs taken from the bottom of it.

The Bastei Bridge rises above the Elbe River in Germany’s Saxon Switzerland National Park.
The Bastei Bridge has been a tourist attraction for over 200 years. In 1824, a wooden bridge was constructed to link several rocks for the visitors. This bridge was replaced in 1851 by the present Bastei Bridge made of sandstone. Reaching a height of 194m (636 feet) and 305 meters (1 000.65 feet) above sea level, the jagged rocks of the Bastei were formed by water erosion over one million years ago.
