Scuba Diving the Blue Hole in Belize

“The Great Blue Hole”, also known as “The Blue Hole of Belize” is a huge marine cavern (sinkhole) and one of the most magnificent places on our Planet. Further, it is among the most popular destinations for Scuba Diving.

It is worth to mention that biologist Charles Darwin (1836) characterized Belize’s Blue Hole as the most remarkable and richest coral reef in Central America.

Thousands of Scuba divers have already visited Belize in order to explore the Blue Hole, its crystal clear waters and a wide variety of spectacular species. Caribbean Reef Shark & Midnight Parrotfish are some of them.

Where exactly is “The Blue Hole”?

It is in Belize which is an independent country of Central America (north-eastern coast) between Mexico, Guatemala and the Caribbean Sea on its Eastside.

The “Great Blue Hole” is located close to Lighthouse Reef’s center, a coral atoll 70km (43mi) away from Belize City.

The Great Blue Hole is circular in shape with a length of 318m (around 1,040 ft) and depth of 124m (407 ft).

Scuba Diving in the Blue Hole

One of the most popular activities you can try in Belize is to Scuba dive in its waters, especially in the “Blue Hole”. Many tourists each year visit the country mostly for experiencing the feeling of scuba diving on the circular hole.

You can access the circular hole only by 2 narrow channels as the area is surrounded by the coral reef.

The reef close to Hole’s rim is only a few meters below the sea level; you can see beautiful species of corals, colorful anemones and starlets. This is the reason that is an excellent place for snorkeling as well!

Your dive will begin from either the South or Northside, depending on the weather conditions.

South Side

By diving from the South Side, you can witness the shallowest cave systems at approximately 30m (100ft). It’s not hard to notice that the wall’s angle changes, leading to stalactites that are wider than 3ft and up to 20ft long.

As you continue, the dive becomes more intense by the sight of stalagmites pointing upwards, reminding the jaws of a giant shark! After this, there is an entrance that leads to a cavern system that adds a mysterious feeling for the curious divers.

North Side

The first part of a North Side dive seems similar to the south side. You can see rows of stalactites at about 30-40m (101-141ft), but in contrast with the south side, there are no stalagmites.

The bottom below this point is deeper than 80m (+250ft) and remains almost unexplored due to a large mound of debris and sand.

Ascending Up

After you have admired the beauty of strange rock formations and head your way up, you may encounter Caribbean Reef Sharks or other unique Shark species that are patrolling the reef.

These kinds of sharks are not dangerous to humans unless provoked repeatedly. Anyway, you have nothing to be afraid of, as long as you stay close and follow your guide’s instructions.

If you need to discharge some nitrogen that you absorbed during the deep dive, the coral reef at hole’s rim is probably the best place to do that. There, you can witness colorful kinds of fishes such as Butterflyfishes, Anglerfishes & Groupers.
