North Sentinel Island: The Forbidden Island of the Bay of Bengal

Hidden deep within the Bay of Bengal lies North Sentinel Island, an untouched and mysterious world. This remote island is home to the Sentinelese people, one of the last truly uncontacted tribes on Earth. Their complete rejection of modern civilization makes the island both fascinating and dangerous, capturing global curiosity while underscoring the need to protect its indigenous inhabitants.

The Sentinelese: One of the World’s Last Isolated Tribes

A Civilisation Untouched for Over 50,000 Years

The Sentinelese are believed to have inhabited North Sentinel Island for tens of thousands of years, living as hunter-gatherers completely independent of modern society. With no evidence of agriculture or metalworking, they thrive using simple tools crafted from stone, wood, and occasionally scavenged shipwreck materials. This long isolation has allowed their culture to remain entirely self-sufficient and resilient.

A Fierce Rejection of Outsiders

Attempts to approach the island have consistently been met with hostility. Whether fishermen, explorers, or officials, outsiders are often driven away with bows and arrows. This is not aggression without reason—the Sentinelese protect themselves from foreign threats and preserve their way of life.

The Danger of Disease

Even minor illnesses like the flu or measles could devastate the Sentinelese, who have no immunity to modern pathogens. For this reason alone, direct contact is considered illegal and morally irresponsible.

Where Is North Sentinel Island?

Part of the Andaman and Nicobar Islands

North Sentinel Island lies west of the southern tip of the Andaman Islands, within Indian territory. Covering around 60 square kilometres (23 square miles), the island is dense with tropical forests fringed by coral reefs and shallow lagoons, making it nearly impossible to land by boat.

Protected by Law and Geography

The Indian government enforces a three-mile exclusion zone around the island. Entry is prohibited to protect visitors from harm and shield the Sentinelese from unwanted intrusion.

Why the World Leaves the Sentinelese Alone

Strict Indian Government Policy

Recognising the tribe’s vulnerability, India has banned all travel to North Sentinel Island. The policy prioritises tribal sovereignty, ensuring the Sentinelese are left to live freely without forced contact.

Tragic Encounters Prove the Risk

The danger of approaching the island became widely known in 2018, when an American missionary was killed after illegally attempting to make contact. This incident served as a stark reminder that any intrusion could lead to violence and cultural destruction.

Protecting Culture and Humanity

Anthropologists and human rights organizations agree that leaving the Sentinelese undisturbed is the only ethical option. Historical encounters with other indigenous groups show that forced contact often leads to catastrophic population decline, cultural collapse, and the loss of traditional knowledge.

The Allure of North Sentinel Island

The mystery of North Sentinel Island has drawn global attention, appearing in documentaries, news headlines, and countless online discussions. Yet the fascination must be tempered with respect: this is not a tourist destination, but a living reminder of humanity’s ancient past.

Plenty of beautiful beaches and cultural attractions are open to travellers curious about the Andaman and Nicobar Islands, but North Sentinel Island is strictly off-limits, for good reason.
