The North Sentinel Island, located in the Bay of Bengal, is home to the Sentinelese people, an indigenous tribe that has chosen to remain isolated from the rest of the world. The island is protected by the Indian government to preserve the Sentinelese way of life. With a history of violent encounters with outsiders, the island remains a mystery, with the Sentinelese living a traditional hunter-gatherer lifestyle, untouched by modern technology.
