This L shape cave is really great. The Cave, or more accurately, “The Tunnel”. Journey underneath Gato Island and come out the other side! This 30m tunnel houses all the usual cave dwellers: many types of crab big and small, lobsters and cardinal fish. You should also encounter some large puffer fish and perhaps bamboo and cat sharks. Once in, just go to the surface and watch the bats! Then go back to the bottom and continue to the NW. There is a nice lightening window on the right (good for photographers). Turn left and you should see the exit.
