Ni'ihau

Ni'ihau is the northern most of the 8 main Hawaiian islands and is the smallest of the inhabited islands. It is often referred to as "The Forbidden Island," because it  has been privately owned by a single family since 1864. The island has no electricity, TVs, hospitals, or other amenities. They live a traditional lifestyle and speak Hawaiian as their first language. The Ni'ihau incident occurred during attack in WWII when a Japanese pilot crashed on the island and committed a load of chaos before being killed.
Presently, Keith Robinson fights to preserve the way of life for the islands residents and continues to cultivate endangered Hawaiian flora. The island is also an important refuse for various endangered indigenous fauna including several bird species and the Hawaiian Monk Seal.
