North Sentinel Island
North Sentinel Island is part of the Indian Andaman Islands, and is populated by the Sentinelese tribe. It may sound like a legend, but the Sentinelese tribe is one of the few tribes that remain completely untouched by modern civilization.
The Sentinelese remained disconnected from civilization by choice – they reject any contact with the outside world, often violently. Thus, they are considered extrmely aggressive and dangerous.
