North Sentinel Island located in the Bay of Bengal lies west to the archipelago of Andaman Islands. Most of the island is heavily forested, surrounded by coral reefs and it lacks a natural harbor.
The island is popular due to the Sentinelse people, who inhabit the island. They reject any contact with any outsider to the island and are among the last people to remain virtually untouched by modern civilization.
The islanders survived the 2004 Indian Ocean earthquake and tsunami that led to uplifting of the island.
Various expeditions have been ordered to establish friendly contact with the tribe by presenting them with coconuts, buckets, dolls, pigs and metal pots.
