If you are a diving enthusiast, this Blue Hole in Belize is a must visit spot on Earth. The Great Blue Hole is located in Belize Barrier Reef Reserve System, about 60 miles away from Belize City. It is believed that this hole is the world’s largest sea-hole. It is about 125 meters deep and its diameter is about 300 meters wide. It has been created as a cause of sea level increase about 65,000 years ago.
This is a popular spot amongst recreational scuba divers, who are lured by the opportunity to dive in crystal-clear water and meet several species of fish, including giant groupers, nurse sharks and several types of reef sharks such as the Caribbean reef shark and the Blacktip shark. Other species of sharks, like the bull shark and hammerheads, have been reported there, but are not regular sightings. Usually, dive trips to the Great Blue Hole are full-day trips, which include one dive in the Blue Hole and two further dives in nearby reefs.
