The Andaman and Nicobar Islands are a group of nearly 600 islands in the Bay of Bengal. Although part of India politically, they are closer to Indonesia and Myanmar than to the Indian mainland.
Most people come here for the beaches and scuba diving, especially on Havelock Island and Neil Island. The best dive sites in the Andamans are in remote locations and are impossible to get without a private yacht charter. The dive sites around Havelock are actually very ordinary by Andamans standards.
The only place with historical attractions of note is Port Blair, which houses British-era colonial buildings, including the notorious Cellular Jail, and a few World War II bunkers dating from the brief Japanese occupation.
