A coral reef off the south coast of Cuba, previously reported by Robert Osborne in August 2023 to experience a bleaching event, has shown a remarkable recovery in 2025.
There are wonders to discover and explore in Cuba’s natural world, both above and below the surface of the sea, from endemic species of marine life to exotic birds and animals in the national parks. Pierre Constant shares his journey there.
As global warming heats up oceans around the world, coral bleaching events are increasing in frequency and severity. Robert Osborne reports on how climate change has impacted his favourite coral reef in Cuba.
Researchers from the Woods Hole Oceanographic Institution (WHOI) and the Centro de Investigaciones Marinas—Universidad de La Habana (CIM-UH) have discovered that offshore coral reefs that are also protected tend to be healthier than nearshore ones.
In the study, seawater from 25 reefs in Cuba and the Florida Keys in the US were tested for nutrients and other parameters that would give researchers a glimpse into the microbial community present.
The law in the US still prohibits tourist travel to Cuba, but a dozen other categories of travel are permitted, including family visits, official business, journalist visits, professional meetings and educational and religious activities. The Obama administration has eased rules to the point where travelers are now free to design their own “people-to-people” cultural exchanges with little oversight.
The Cuban government is environmentally minded. In 1996, the 837-square-mile marine area and archipelago of Gardens of the Queen located south of the main island of Cuba became a no-take reserve—the largest in the Caribbean—and in 2010 was designated a national park.
As the wheels touched down at Havana’s International airport, the plane erupted with cheers and applause. Many of the passengers on board had waited years, if not decades, to return home and visit relatives in Cuba. As part of a small group of Americans visiting for the first time, I knew immediately that we were in for a special treat.
