Never ever go to this beach
The Sentinelese people of North Sentinel Island are part of the Andaman and Nicobar Islands in the Indian Ocean...and are said to have lived in isolation for thousands of years by now.
Any traveler who's attempted to step foot on their island has been killed, or sent back to their boat in bad condition. The Indian government has even created a three-mile exclusion zone to prevent unwanted civilian casualties.
In 2006, two fishermen who were fishing illegally inside the exclusion zone were killed by the Sentinelese and buried in shallow graves. When a helicopter attempted to retrieve the bodies, it was shot at with arrows until it was forced to retreat.
Thick canopy of trees covers the island, which is the size of Manhattan. Many of the islanders hide when an outsider is near, but it's believed there are 40-500 of them. The tribe is considered "stone age," as it only survives by scavenging things that was up ashore.
