The Great Blue

The Great Blue Hole is a massive, circular underwater cavern near Belize’s coast, best known for its vibrant blue color. Formed over thousands of years through limestone erosion, it measures about 1,000 feet (300 meters) across and over 400 feet (125 meters) deep. It's a popular spot for divers due to its unique geology, clear waters, and diverse marine life. The blue appearance results from the depth and clarity of the water, creating a striking, otherworldly scene. The Great Blue Hole is both a natural wonder and an important site for scientific study of carbonate formations and marine ecosystems.
