We visit Tyrell Bay, Carriacou (north of Grenada) to talk with Richard and Diane, owners of a local dive operation steps from the beach. They share how they built a relaxed, concierge-style shop—complete with a private jetty and dinghy pickups for cruisers—and why Carriacou's 38 dive sites keep photographers and explorers coming back. We break down two signature dives—Sisters Rock and Tropical Hill—plus the island's hands-on fight against the invasive lionfish (weekly culls, restaurant partnerships, even artisan jewelry). Most sites sit inside the Sandy Island Oyster Bed Marine Protected Area, where biomass and juvenile fish thrive. Hear how teaching local eels to predate lionfish reduced sightings on popular reefs and why Carriacou feels like "old-school Caribbean" diving done right.
