Snorkeling and Diving
American Samoa is very modest when it comes to clothing. When swimming or snorkeling be sure to not wear short and revealing swim suits (i.e. bikinis and brief style trunks).
American Samoa does not have much of a tourist diving infrastructure, so you should bring most of your gear and plan to rent only your air tanks. Dive from shore on Tutuila Island, the largest island in the American Samoa archipelago and your starting point in the area. Due to the lack of tourists in American Samoa, there are no regular boat diving trips to offshore sites, so any such trip must be planned and paid for on a charter basis.
