Great Blue Hole

The Great Blue Hole is a very big hole in the ground. It is a circle and it is very deep. It is in the ocean near a place called Belize.

It is special because it used to be a big cave a long, long time ago before the water covered it. Now, when you look down into the hole, you can see lots of different colors. Sometimes you can see fish swimming around and sometimes you can even see sharks!

People really like to go scuba diving in the Great Blue Hole because it is so big and deep and because there are cool things to see.
