A barrier reef runs along the eastern, Atlantic-facing side of Canouan, sheltering a series of calm turquoise lagoons. The coral is in good health and the water clarity is exceptional — visibility frequently exceeds 30 metres. Snorkelling is possible directly from the beach without a boat; diving operators are based at the resort on the northern half of the island.
The reef supports a varied ecosystem: eagle rays, spotted moray eels, queen angelfish, and the occasional nurse shark are all regular sightings. The nearby Tobago Cays, reachable by day charter, offer some of the finest snorkelling in the entire Caribbean.
