Off the northwest shore of Anegada, the snorkeling at Cow Wreck offers great shallows to explore. The Cow Wreck Beach snorkel spot is within Walk Over Set Bay just in front of the Cow Wreck Beach Bar, which is a good place to grab a cool drink afterwards.
To reach Anegada Island, there is a ferry from Tortola, or you can take a private air charter.
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.
