Northeast of Spanish Town and just south of Gun Creek, the snorkeling at South Side Reef offers an offshore barrier reef to explore. In addition to the outer reef, there is a smaller inner reef, both of which have good formations of star coral and staghorn coral. With waters around 10 feet deep, the reefs provide habitat for wrasse, grouper and parrotfish. South Side Reef is located within Little Bay and bordered by Dog Bay.
To reach the snorkeling in the British Virgin Islands by air, you will need to fly into either Virgin Gorda Airport (VIJ) or nearby St Thomas Airport (STT) in the US Virgin Islands. Virgin Gorda Airport is served by inter-island flights from San Jose, Puerto Rico (SJU) by Cape Air and Seaborne. St Thomas Airport has flights from mainland US and also from San Jose. There are several regular ferry services connecting St Thomas with Tortola and Virgin Gorda. In addition, there are BVI inter-island ferries interconnecting Virgin Gorda, Tortola, Jost Van Dyke and Anegada. When leaving BVI, there is a $20USD depature tax that must be paid in cash.
Overall, South Side Reef is the 21st most popular snorkel dive spot of all 27 snorkeling dives in British Virgin Islands.
