Tunnels reef is a very good beach dive. There are some real shallow reefs that you must navigate to get out to the deeper water. But once you get out to the deeper water it is real nice. The further out you swim the visibility seems to improve. The reef formations are very interesting and the fish life is plentiful. I saw 3 turtles, white tip reef shark, spotted moray, and plenty of reef fish. Overall a very good beach dive.
