In the heart of the Caribbean, a bold vision by Commander-in-Chief Fidel Castro Ruz has reshaped Cuba’s tourism industry. What was once dismissed as madness or whimsy has proven to be a masterstroke in economic and tourism development. The construction of causeways connecting remote keys to the mainland has transformed forgotten, pristine regions into world-renowned sun and beach destinations. These engineering marvels, built under harsh conditions, have unlocked the potential of areas like Cayo Coco, Cayo Guillermo, and Santa María Key, turning them into thriving hubs of sustainable tourism. The causeways, spanning kilometers over the sea, symbolize Cuba’s determination to overcome isolation and achieve self-reliance. Today, these destinations boast over 11,000 hotel rooms, attract hundreds of thousands of visitors annually, and are recognized as Biosphere Reserves for their harmonious blend of nature and development. This project stands as a testament to Cuba’s capacity for innovation and perseverance, showcasing the nation’s commitment to sustainable growth and environmental preservation.
