Port Blair is capital and largest city of the Andaman and Nicobarisland group, with a population of around 100,000.
Given the beauty of the rest of the Andamans, Port Blair is an upcoming city no different from any other smaller Indian city, although the seaside has been tarted up a bit. It comprises of people from all over India and one can imagine it as mini India with no conflicts on region and religion. Aside from Cellular Jail, there are quite few places which include Ross Island, Barren Island (known for the only active volcano) and few others known for its historical importance. A week's trip will cover the must see places at the island's. You can however do day trip to other close by places like Wandoor, Ross Island etc.
