Great Blue Hole
Belize · Lighthouse ReefNear Gran Agujero Azul
A cave whose roof collapsed millennia ago and which then flooded. It forms an almost perfect circle some 300 m across at the surface and drops vertically to around 124-125 m. Recreational diving reaches 40 m, the depth at which the stalactites appear: the largest formations of their kind ever found underwater.

Did you know
Lo popularizó la visita del Calypso de Cousteau en 1970 y el nombre se lo puso el escritor y buceador británico Ned Middleton. Es una inmersión de emoción, no de fauna: por debajo de los 30 m la narcosis es un riesgo real y el sitio se ha cobrado vidas. Belice tiene tres de los cuatro únicos atolones coralinos verdaderos del hemisferio occidental: Lighthouse Reef, Turneffe y Glover's Reef. El bien estuvo en la Lista del Patrimonio Mundial en Peligro entre 2009 y 2018; salió de ella después de que Belice aprobara una moratoria que prohíbe la exploración petrolífera en toda su zona marítima.
