We would like to introduce you to the Great Blue Hole of Belize. This is a natural sinkhole that is about 1000 feet across and close to 500 feet deep. it is ringed by stalagmites, and there is even a cave that you can reach near the blue hole. It is one of the largest Blue Holes in the world, and some of the stories (like the one inside) from the blue hole in Belize are amazing.
