Journey to Cuba's underwater Eden

Earlier this year, EDF senior writer Rod Griffin embarked on a scuba expedition to the Jardines de la Reina, or Gardens of the Queen, a spectacular undersea reserve off Cuba’s southern coast that has been off-limits to U.S. divers for more than 50 years.

Rod kept a diary of his 10-day-long adventure in the company of some of the world’s leading marine experts. Funded by the Waitt Foundation, the trip offers a rare glimpse of this underwater Eden, while underscoring the environmental threats facing even a relatively unspoiled patch of ocean.
