Travel guide

The Commonwealth of the Northern Mariana Islands (CNMI) is a territory of the United States in Micronesia, visited mainly by tourists from East Asia. The Marianas' top activity among Americans is scuba diving and snorkeling. In addition to the coral reefs you might expect, the waters around the islands were the scene of fierce fighting during World War II and there are many ship wrecks and even rusting tanks stuck on the seabed. Many Asian visitors come to the CNMI for gambling, and karaoke/hostess bars.
