Diving is probably the number one reason to come to Saipan, as the island caters to divers of all experience levels. Explore wrecks and reefs within protected lagoons or enjoy the dramatic drop-offs and blue-water dives.
US currency is used throughout Micronesia (with the exception of the Republic of Kiribati which use Australian currency). Outside of Guam and Saipan, the use of credit cards is very limited, although major hotels on all islands take them.
