    The MG-111 barge doesn't get the same buzz as some of the Keys' bigger wrecks, but we think that’s part of its charm. It’s a fantastic little find if you’re looking for a relaxed wreck dive without the crowds. You'll find it fairly broken up, sprawled across the sand in manageable sections, which makes it perfect for a leisurely explore. We love poking around the scattered metal plates, where grunts and snappers school up, darting in and out of the shadows. It's not a wreck you penetrate, but the way the current has worked on it means there are plenty of nooks and crannies to peer into. Look closely for those tiny cleaner shrimp waiting for a customer, or a shy moray peeking from under a steel beam. Visibility here is often better than you might expect, especially on an incoming tide, giving you a really clear view of the structure and the fish life that calls it home. This site really suits divers who appreciate the subtle beauty of an artificial reef taking hold, rather than those chasing a deep, intact wreck.
