#2: North Sentinel Island

North Sentinel Island in the Bay of Bengal is renowned for its reclusive Sentinelese inhabitants, who have shunned contact with modern civilization. This indigenous group remains fiercely independent, often meeting outsiders with hostility to protect their way of life.

Their isolation has preserved their unique culture and lifestyle, which also means they lack immunity to common diseases. Consequently, strict advisories are issued against visiting the island, both to protect the Sentinelese from potential harm and to respect their desire for seclusion.
