Buccoo Reef is the most accessible coral system in Tobago, lying just offshore from the southwestern tip of the island. It extends for several kilometres and encompasses several distinct habitats: coral gardens, seagrass beds, and the famous Nylon Pool — a shallow sandbar of white sand in the middle of the lagoon. Glass-bottom boat tours depart regularly from both Pigeon Point and Store Bay, typically lasting about two hours and including a snorkel stop over the reef and a swim in the Nylon Pool.
The reef supports abundant fish life including parrotfish, triggerfish, angelfish, and sergeant majors. Turtles are sometimes spotted resting on the outer sections. For serious snorkellers, the water clarity and fish density in the better-protected outer sections rival anything in the Caribbean. The Tobago Cays Marine Park system has improved reef governance somewhat, and coral cover in undisturbed sections has begun recovering from bleaching events in the early 2000s.
