SITUATED ON THE NORTH WEST COAST LINE OF TANNA ISLAND, THIS TANNA ATTRACTION IS NOT TO BE MISSED! Whether you are a keen snorkeler or not, you will be enthralled by the beauty of this place. Once you arrive to Blue Cave either by boat or road it is an easy swim into the cave, at low tide you can swim right under the rock ledge that takes you into the cave and at high tide you will need to swim underwater for a very short distance, where you will then come up in the cave. The cave is quite large and has a hole in the roof that provides a beautiful light, which shines into the cave highlighting the blue water and creating great photo opportunities. You do not need to be an experienced swimmer but if you feel a little nervous about diving underwater to enter the cave then you should visit the Blue Cave at low tide. If you make your own way to the cave with a boat, yacht or 4WD an entrance fee of 2000 vatu per person is required to be paid in cash.
