The Great Blue Hole, a stunning, deep blue circular sinkhole and part of the Belize Barrier Reef UNESCO World Heritage Site, lies within the Lighthouse Reef atoll. Spanning approximately 1,000 feet (305 meters) in diameter and plunging over 400 feet (122 meters) deep, this unique geographic phenomenon is recognized as one of the world’s top diving sites. Divers can explore its crystal-clear waters, where they may encounter stalactites and diverse marine life, making it a remarkable destination for underwater enthusiasts.
