13 Unique Caribbean Eco-Adventures for American Explorers

5. Caving in Rio Camuy Cave Park, Puerto Rico

Puerto Rico’s Rio Camuy Cave Park invites adventure seekers to journey through a subterranean world sculpted over millions of years. As one of the world’s largest cave systems accessible to the public, the park reveals dramatic chambers, sinkholes, and a living river flowing beneath limestone cliffs. Guided tours offer safe pathways for both beginners and experienced spelunkers. The park partners with local conservationists to balance exploration with preservation. Rangers focus on teaching about the delicate cave ecosystem, including unique bats and insects found nowhere else. Responsible caving means not straying off marked trails and respecting access closures during the wet season. Booking ahead is wise, as visitor numbers are controlled to protect sensitive formations. U.S. travelers appreciate that tours are conducted in English and tailored to reveal geological marvels—making each descent a blend of responsible tourism and sheer natural spectacle.
