Dave and I did a couple of dives at French Reef today. Water temps are holding around 80 degrees. Although you do not see a lot of coral growth on this reef, the reef structure is interesting. There are are lots of swim throughs the coral heads and some need “caves” you can enter, as see in this video. SCUBA divers are allowed to enter caverns without Cave certification as long as they remain in sight of the exit at all times. Sand Cave seen in this video meets that criteria. It is a cool experience to see the streams of light coming through the roof of the cavern and your bubbles collecting on the ceiling.
