The Belize Blue Hole, one of the top ten geological wonders in the world, is located on the lighthouse reef on the edge of the submarine plateau of the Grand Bahama Shoal in the Bahamas Islands in the Caribbean, about 100 kilometers away from Belize City, the capital of Belize. During the Ice Age, it was a large dry cave. Later, as the glaciers melted and the sea level rose, it became what it is today. The entrance of the cave is perfectly round, and coincidentally coincides with the surrounding atoll.
The Belize Blue Hole has a diameter of 400 meters and a depth of about 145 meters. It is precisely because it is deep enough that it presents a dark blue scene, which is so profound and mysterious that it looks like the pupil of the sea from a high altitude.
Because of this, this structure is called a "Blue Hole".
In the Belize Blue Hole, there are also a large number of stalactites, a wide variety of sharks, and many underwater caves, making it aOne of the most famous diving destinations in the world.
