Misconceptions About the Great Blue Hole Atoll

Tobacco Caye Atoll

Many believe that the Great Blue Hole lies near the center of Tobacco Caye Atoll. However, this is not the case. The Great Blue Hole is actually located in Lighthouse Reef Atoll, which is approximately 70 kilometers from the Belizean mainland. It is important to note that while Tobacco Caye is a picturesque island within the vicinity, it is not the atoll in which the Great Blue Hole is situated.

Turneffe Atoll

Glover’s Reef Atoll, another breathtaking atoll in Belize, might be mistakenly associated with the location of the Great Blue Hole. The misunderstanding likely arises due to the proximity of these atolls and the similar appeal they hold for diving and marine adventure enthusiasts.
