West of Scarbourgh and northeast of the airport, the snorkeling at Mount Irvine Bay offers plentiful marine life to observe. The best snorkeling in Mount Irvine Bay is located near the rocks off of the Mt Irvine Bay Beach Hotel where you may find tangs, wrasse, christmas tree worms, feather duster worms, stingrays and possibly manta rays. This is a family-friendly shore or boat accessed snorkeling dive site. While some beginners do head out into these waters, you do need to be aware of potentially strong currents at this dive site. The main dive site is located just off-shore of the center of Mt Irvine Bay.
For strong snorkelers, they can head further out to Dutchman Reef in the middle of Mount Irvine Bay. Also known as French Wreck Reef, the water depths are around 15 feet and harbor several cannons from the old wreck.
The shallow water reefs surrounding Tobago are very popular for snorkeling. These water are filled with great diversity of reefs, rock pillars, wrecks and extravagant undersea gardens filled with giant sea fans, whips and plumes. The reefs are home to over 300 different species of coral including staghorn, elkhorn, fire coral, brain coral and starlet coral. There are giant tube sponges that also attract numerous angelfish. Generally, there are moderate to strong currents at most snorkeling dive sites, so there are few options for moored snorkeling dive boats.
When considering a Tobago snorkeling trip, keep in mind that, for the Caribbean, there is a shocking change in water temperature with season. February and March are known for the coldest water temperatures (as low as 68F). With the rainy season starting in June, the best months for snorkeling are late April and May.
To reach Tobago snorkeling by air from Europe, fly into Arthur Napoleon Raymond Robinson International Airport (TAB) in Crown Point on the southwest point.
To reach Tobago snorkeling by air from North America, fly into Piarco International Airport (POS) on Trinidad located southeast of Port Of Spain. There is a twice-a-day ferry service (4 hours) and seacat service (2 hours) between Trinadad and Tobago.
Overall, Mount Irvine Bay is the 17th most popular snorkel dive spot of all 20 snorkeling dives in Tobago.
