Which island is known as the Forbidden Isle?

The island known as the Forbidden Isle is Ni'ihau. This designation arises from its restricted access, as the island is privately owned and has limited visitation allowed, primarily for family members of the landowner and select guests. Because of its exclusive nature, it has retained much of its traditional Hawaiian lifestyle and culture, making it distinct from other islands in Hawaii that are more accessible to tourists. While other islands like O'ahu, Kaua'i, and Lana'i offer various attractions and are open for tourism, Ni'ihau remains largely untouched and preserves a unique cultural heritage. This isolation contributes to its nickname as the Forbidden Isle.
