The Kaminaki cave is located between Nisaki and Kaminaki beach. The entrance of the cave is 15 metres wide and approximately 5 metres high. The maximum length of the cave is 100 metres. The Kaminaki cave is richly decorated with stalagmites and stalactites and full of big rocks. In 2018 a few cave crickets were seen and some animal bones were found in the cave. The story that the cave has 7 levels and that it is ends up in sea is not true.
