North Sentinel Island remains one of the most mysterious unexplored islands in the world.
North Sentinel Island is one of the Andaman Islands in the Bay of Bengal. It lies to the west of the southern part of South Andaman Island.
Most of the island is forested. It is small, located away from the main settlements on Great Andaman, surrounded by coral reefs, and lacks natural harbors.
A group of indigenous people, the Sentinelese, live on North Sentinel Island. Their population is estimated to be between 50 and 400 individuals.
The Sentinelese reject any contact with other people and are among the last people to remain virtually untouched by modern civilization.
The population faces the potential threats of infectious diseases to which they have no immunity, as well as violence from intruders.
The Indian government has thus declared the entire island, which is approximately the size of Manhattan, and its surrounding waters extending 3 miles from the island, to be an exclusion zone.
