The Forbidden Island In India, North Sentinel Island

Located in the midst of the Bay of Bengal, the North Sentinel Island is home to the indigenous tribal group named Sentinelese. They are known to be hostile to the outside world and, at times, even attack foreigners in their land. Given this behavior, the Indian government decided to ban entry into the island in recent times.

In fact, after the devastating Tsunami of 2004, many humanitarian missions and rescue helicopters were sent out to help them, but all of them were attacked with arrows. This makes the Sentinelese one of the most isolated and dangerous tribes of the world.
