Along the fan-shaped northern crown of Antigua, there are several snorkeling dive sites in Dickenson Bay. The dive sites are located about 1.5 miles west of Cedar Grove.
To reach the snorkeling on Antigua by air, you will want to fly into VC Bird International Airport (ANU) located on the northeast corner of Antigua. Most of the flights are coming from San Juan, Puerto Rico, from St Martin, from Barbados and from Trinidad. There are some smaller inter-island airlines that service other nearby Caribbean islands. In addition, there is the Barbuda Express ferry service to nearby Barbuda (1.5 hours) that runs five days a week. The best way to get around Antigua is by renting a car since taxis are very expensive and the public transport is not ideal. When leaving the island, there is a $28USD departure tax and a $51USD airport tax that must be paid (most airline tickets have included both, but you will want to confirm since the payment lines at the airport can be quite long). While snorkeling Antigua, there is very diverse marine life around the island including hawksbill turtles, sergeant majors, spadefish, batfish, moray eels, barracuda and nurse sharks among the sea fans, sea grass, sponges and colorful coral reefs. There are numerous snorkeling boat tours that access the most popular snorkel dive sites including Treasure Island Cruises, Pirates Of Antigua and Adventure Antigua Day Sails. If you happen to be snorkeling in Antigua on a Sunday, make sure to head up in the evening to Shirley Heights, which is located on a hill that overlooks English Harbour. There is a Sunday evening BBQ and rum punch along with fine reggae music.
Overall, Dickenson Bay is the 5th most popular snorkel dive spot of all 14 snorkeling dives in Antigua.
