It is believed that these caves were once air-filled and stood high above sea level thousands of years ago.

Diving into the Great Blue Hole is an unforgettable experience. As divers descend, the dark waters gradually become clearer, revealing a complex network of flooded caves adorned with stalactites, stalagmites, and other limestone formations. The deeper one ventures, the more intricate and captivating the scenery becomes. However, diving in the Great Blue Hole is not for the faint-hearted or inexperienced. It is a complex and challenging dive due to its depth and the specialised skills required.

The Great Blue Hole is also notable for its diverse marine life. While the deeper areas of the hole have limited marine life due to reduced light and water circulation, the shallower waters teem with a variety of species. Divers may encounter hammerhead sharks, blacktip tiger sharks, bull sharks, Caribbean reef sharks, groupers, angelfish, shrimp, and a plethora of tropical fish and coral types in the surrounding waters.

The Great Blue Hole is more than just a diving destination; it is a natural wonder that captivates the imagination. Its formation over thousands of years, its immense depth, and its striking circular shape visible even from space, make it a truly extraordinary phenomenon.

The Blue Hole is a UNESCO World Heritage Site and one of the seven wonders of Belize

The name of the blue spot in Belize is the Great Blue Hole. It is a giant marine sinkhole off the coast of Belize, near the centre of Lighthouse Reef. The Great Blue Hole is indeed a UNESCO World Heritage Site, having been designated as one in 1996. It is part of the Belize Barrier Reef Reserve System, which is a World Heritage Site of the United Nations Educational, Scientific and Cultural Organization (UNESCO).

The Great Blue Hole is also considered one of the seven wonders of Belize. In 1997, CNN listed their seven natural wonders of the world, which included aquatic sites. The Great Blue Hole was then nominated to be the eighth wonder of the modern world by VirtualTourist.com.

The Great Blue Hole is a popular destination for recreational scuba divers, who are attracted by the opportunity to dive in crystal-clear waters and observe a myriad of species of marine life, including tropical fish and coral formations. The site was made famous by Jacques Cousteau, who declared it one of the top five scuba diving sites in the world.

The Great Blue Hole is a vast expanse of interconnected underwater caverns adorned with remarkable formations such as stalactites, stalagmites, dripstone sheets, and columns. Scientists believe that these structures originated within the caverns long before the area became submerged. The hole is circular in shape, over 300 metres (984 ft) across and 125 metres (410 ft) deep. It is the largest natural formation of its kind in the world.

The Belize government, recognising the cultural and ecological importance of the Great Blue Hole, has collaborated with several environmental organisations to safeguard its preservation. This includes implementing rigorous diving regulations and placing limitations on visitor numbers to protect the site and ensure its long-term well-being.

It is a popular diving destination, but only for experienced divers

The Great Blue Hole in Belize is a popular diving destination, but only for experienced divers. This is due to the complexity and depth of the dive, which requires advanced skills and qualifications. The Blue Hole is a giant marine sinkhole located off the coast of Belize, with a depth of approximately 400 feet and a circumference of 3,140 feet. It is considered one of the most iconic and astounding dive spots in the world.

The Blue Hole is part of the Lighthouse Reef, a small atoll located about 60-70 miles from the mainland of Belize City. The unique challenge of diving in the Blue Hole attracts divers from around the world. However, only experienced divers with the necessary qualifications are permitted to explore its depths. To be qualified to dive in the Blue Hole, individuals need at least an Open Water or Advanced Open Water diving certification. Even with the required certifications, divers typically practice their skills with a divemaster who will assess their readiness for the Blue Hole dive.

The Blue Hole dive is not for the faint-hearted or inexperienced. It involves descending to a depth of 130-135 feet, where divers can explore the stalactites, stalagmites, and other limestone formations that adorn the walls of the sinkhole. The array of bizarre stalactites and stalagmites become more intricate and intense as divers go deeper. The water temperature at this depth is a constant 76°F throughout the year.

As divers venture deeper, the reduced light levels add a gothic atmosphere to the experience. Experienced divers can push their limits and go down to around 270 feet to explore underwater dunes and bedrock ledges. However, it is important to note that the Blue Hole dive is a technical category decompression dive, and it is not recommended for beginners or resort-qualified divers. The bottom of the Blue Hole is over 400 feet down, and divers need absolute buoyancy control to avoid a dangerous descent or ascent.

The Blue Hole is a once-in-a-lifetime diving experience that offers a unique opportunity to explore a flooded cave system with stunning geological formations. It is a testament to the popularity of the Blue Hole as a diving destination that legendary explorers like Jacques Cousteau and Bill Gates have visited and praised it as one of the top diving sites globally.

The Blue Hole was explored by Jacques Cousteau in the 1970s, who declared it one of the best diving spots in the world

The Great Blue Hole, a large underwater sinkhole off the coast of Belize, was explored by Jacques Cousteau in 1971 (or 1972, according to one source). Cousteau, a French naval officer, conservationist, filmmaker, innovator, scientist, photographer, author, and researcher, is considered the father of scuba diving. He brought his renowned research ship, the Calypso, to the hole to investigate its depths and chart its depths.

Cousteau's expedition found some submerged stalactites in the hole, confirming that it was formed before ocean levels rose. The discovery of stalactites also revealed that the sinkhole was once a cave system above sea level. This is because stalactites are formed on cave ceilings on land. Further analysis of these stalactites revealed mineral compositions that could only have been formed when the cave was above sea level.

Cousteau's exploration of the Great Blue Hole was featured in an episode of his popular television series, "The Undersea World of Jacques Cousteau", which aired in the 1970s. The episode, called "Secrets of the Sunken Caves", captured the attention of audiences and placed the Great Blue Hole on the bucket lists of scuba divers worldwide.

Cousteau declared the Great Blue Hole one of the top five scuba diving sites in the world. The site is known for its crystal-clear waters and myriad species of marine life, including tropical fish and spectacular coral formations. It is also characterised by its unique geological formations, including stalactites, stalagmites, dripstone sheets, and columns. The hole is over 300 metres across and 125 metres deep, making it the world's largest natural formation of its kind.

The Great Blue Hole is located near the centre of Lighthouse Reef, a small atoll approximately 70 kilometres from the mainland coast of Belize. It is part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site.
