Located off the coast of India, North Sentinel Island is located in the Bay of Bengal. It's a ways away from civilization and no one has been able to make contact with the native inhabitants. The island is one of the last remaining uncivilized places of the earth! An indigenous tribe has lived on the Island with extremely limited contact with outsiders. Anyone who has attempted to explore the island has been attacked or outright killed. North Sentinel is so dangerous for outsiders that India's government has established a three-mile exclusion zone in an effort to prevent more violence.
