Kola Cai Caves are ancient volcanic craters, dating back thousands of years. Created by the island's volcanic activity, these caves have been used for thousands of years as a shelter and a source of water. Professional guided tours take you below the surface to learn about the history of the caves' formation, and helmet, lights, pads and gloves are provided for a crawling tour if required. You can take these tours with friends and family and spend a fun and interesting adventure.
