Water clarity and colour rival anything in the Pacific, and you may go days without seeing another yacht. Declared a national park in 1972.

NOTE, check current entry requirements and security advisories for Venezuela before routing. Hazards: NOTE, check current entry requirements and security advisories for Venezuela before routing. More
