Description: There is no fear of disorientation, because the exit is visible from the entrance. The walls are populated with sponges and corals, while the European lobster tends to inhabit the holes in the walls. In the summer months the tunnel feels as a tropical destination due to the number of fish. After exiting the tunnel head southeast for interesting rock formations and seahorses or northwest for walls covered in smaller red gorgonians.
