The Great Blue Hole – A Natural Wonder
Located off the coast of Belize, the Great Blue Hole is a giant marine sinkhole and one of Earth’s most iconic underwater marvels
Measuring over 300 meters across and 125 meters deep, it lies at the center of Lighthouse Reef, around 100 km from mainland Belize
Its perfect circle and deep blue hue sharply contrast with the turquoise shallows, making it visible even from space
The hole is lined with ancient caves and rock formations, with stalactites formed when the area was once above sea level
In 1971, famed oceanographer Jacques Cousteau called it one of the world’s top ten dive sites putting it on every diver’s bucket list
Divers descend to witness eerie caves and encounter reef sharks, groupers, and the occasional nurse shark
