Speyside is a small fishing village on Tobago's northeastern Atlantic coast, and the island's most serious diving destination. The waters off Speyside are nutrient-rich where Caribbean and Atlantic currents converge, supporting large populations of manta rays, eagle rays, and enormous barrel sponges — some of the biggest in the Caribbean, measuring over 2 metres across. The dive sites here include Japanese Gardens, Kelleston Drain (famous for manta encounters), and the wreck of the Maverick ferry sunk as an artificial reef.
Several dive operators are based in Speyside, all offering similar packages: two-tank dives, certification courses, and snorkelling trips. Trips to Little Tobago for birdwatching typically depart from Speyside Pier, a five-minute boat ride across Batteaux Bay. Non-divers come for the birdwatching: the forest between Speyside and the ridge holds many of the species that make Tobago one of the better birding destinations in the Eastern Caribbean.
