This is the most popular cavern dive in Tinian. With three main entry points into the cavern, most divers enter from the hole on top finding a beautiful room inside. After playing around inside the cavern for a while, the divers can exit through one of the other holes, to dive along the wall or look for beautiful shrimps and crabs within the coral formations on the Grotto. At the end of the dive, look back towards the cavern to see all the bubbles escaping from the inside.
