Forbidden Island: India's Mysterious North Sentinel Where Humans Can't Go

• North Sentinel Island, part of Andaman and Nicobar, is strictly off-limits to humans.
• It's home to the Sentinelese tribe, isolated for ~50,000 years, living as hunter-gatherers.
• The Indian government banned entry (5km exclusion zone) in 1956 to protect the tribe.
• The tribe lacks immunity to common diseases, making outside contact deadly for them.
• Outsiders, including John Allen Chau, have been killed by the tribe for attempting entry.

Why It Matters: North Sentinel Island remains isolated to protect its unique tribe and their survival.
