Great Blue Hole
off the coast of Belize, Belize — Lighthouse Reef Atoll, Belize
The Great Blue Hole is Belize’s most famous marine landmark and one of the most recognisable natural sights in the Caribbean and Central America region. Its attraction lies in its unusual scale and shape: a vast offshore sinkhole set within the reef system, best appreciated by boat, aerial view or diving-focused excursions. Even for visitors who do not dive, the Blue Hole is a powerful symbol of Belize’s marine environment and reef-based tourism. It ranks this high because it is both visually distinctive and deeply tied to Belize’s identity as a marine destination. Official Belize tourism material highlights the reef system and the Great Blue Hole as signature experiences, and that status is reflected across travel writing as well. The site is not a casual beach stop; it is a destination experience that requires planning, which adds to its sense of occasion.
