Diving: Entering Virgin Blue hole from the top of the reef, you will descend through a shaft to a cavern 90 feet (30 m) deep. For photographers/videographers, shooting up toward the surface will provide good silhouette shots. The tunnel exits the reef to the west. A dive light is recommended to enhance the colors of the soft corals and sea fans on the ceiling of the tunnel. The tunnel exit is at 125 feet (40 m). Ascend to 45-60 feet (15 to 20 m); keeping the wall on your right. Swim along the wall, soon you will come to the first of the four canyons. Take your time to explore the many small caves,arches and ledges found along the reef.
