When sailing around Vis Island Green Cave is a nice place to see.
It is a cave with two entrances, connected by a stone pillar. There is a hole in the ceiling of the cave, through which sunlight comes in illuminating it bright green.
Green Cave on Ravnik Island is not as well hidden as Blue Cave on Biševo Island and not as famous as the Blue Cave. There is no problem getting in the cave with the dinghy but it is not as fascinating as in Blue Cave.
Still, it is worth stopping by when sailing by.
