A small inland saltwater lake a mile southeast of Rock Sound is connected by tunnels to the sea. Steps have been cut into the coral on the shore so visitors can climb down to the lake's edge. Bring a piece of bread or some fries and watch the fish emerge for their hors d'oeuvres, swimming their way in from the sea. A local diver estimates the hole is about 75 feet. He reports that there are a couple of cars at the bottom, too. Local children learn to swim here.
