Barge Reef is located along the Glass Breakwater in Apra Habor. The barges were sunk as part of the breakwater construction after WWII. The series of barges make for a great shallow dive. The barges are filled with swim throughs, hard corals, and an abundance of reef life. Be mindful when swimming around the barges as there can be rusty rebar and metal sticking out of the cement. Never attempt to penetrate the interior
