On the south side of Island Vis, from the bay of Rukavac, you will find the small island of Ravnik. Her southwestern side conceals another natural wonder – the Green Cave. Beams of sunlight pass through the crevasses in the cave’s domed ceiling, shooting green colored reflections back and forth within the cave’s interior. The result is a divine effect of green illumination.The cave is called “green“ because of the green relection permeating from the sea floor, resulting from an abundance of green algae located at the rocky base of the cave’s entrance. The Cave has two large entrances and is very accommodating, allowing visitors easy entrance with their motorboats. Swimming is permitted.An exceptional natural phenomenon, it’s an especially attractive spot.
