I snorkeled this today because the dive shop didn't have my tanks! The vis was about 30' once you get out to the main diving area. I dove to the bottom and the vis went up to 50 or 60 feet. Spotted a barracuda so large we thought it was a shark. 3 or 4 feet and thicker than my leg. There were 2 hunters out there. Each had 2 good sized taco. The coral is very sparse. Plenty of tropical fish to see. If a person took their time and explored the lava channels you would find many biological jewels. The walk to the entry is long. You will get hot. Don't leave anything valuable unattended or it will belong to a homeless person by the time you get back. The water is as calm as you can find on the island this time of year. It's not the best site but its easy and very accessible. Spend enough time down there and you'll see some very interesting stuff. Loads of fish under the lava ledges.
