Tobago's Pigeon Point Heritage Park features a long, elegant jetty stretching out over water so impossibly clear and shallow that every starfish and conch shell below is on full display. The beach sits at a narrow spit where the Caribbean Sea and the Buccoo Lagoon meet, creating a bizarre collision of currents and colors. It's the iconic image of the Caribbean that lives in your head before you've ever actually been there — and somehow the real thing is even better.
