Grotta Azzurra, Palinuro by Francesco Riccardo Iacomino
The magic Grotta Azzurra in Palinuro, a wonderful blue cave in the Cilento coast, Italy.
In this cave sunlight creates on the water wonderful blue shades thanks to a siphon (20 m deep) that makes sunlight pass.
It is attainable only by sea (as you can see, the black spot in the bottom is the boat shadow)
