Where can you swim with sea turtles in the Caribbean?

The best places to swim with sea turtles in the Caribbean are Maho Bay on St. John, the Tobago Cays in the Grenadines, and the seagrass bays of the Virgin Islands. Maho Bay is the reliable one — green turtles graze the seagrass in calm, shallow water almost daily. The Tobago Cays go further: a protected marine park with a dedicated turtle sanctuary where snorkelers drift alongside feeding greens and hawksbills. The etiquette is simple. Approach slowly from the side, keep a few body lengths back, never touch or chase, and skip the flash. Turtles surface to breathe, so give them a clear path up. A yacht anchors a swim away from all of it. Start in the US Virgin Islands.
