The Blue Cave
Plava Spilja, Herceg Novi, Montenegro
Description:
The Blue Cave in Herceg Novi is a grotto on the Adriatic coast. The reflection of sunlight at a certain time of day gives the waters of the grotto a special transparent-turquoise color.
The Blue Cave can be reached by boat. Amazing spectral refractions of sunlight in the transparent waters of the grotto give rise to turquoise aurora on the surface of the sea surface. Many shades of blue shimmer along the stone walls, reflected in the waters of the grotto.
Behind the dark and low vault of the cave lies the expanse of a light-drenched grotto. The unexpected transition from pitch darkness to the dazzling glow of the sky is amazing.
In the grotto you can swim by dipping into the water directly from the boat. Thanks to the underground keys, the water in the grotto is several degrees warmer than outside.
