Officially called Inyeug, this tiny islet in Vanuatu is more commonly known as Mystery Island. No one permanently resides here, but its placid turquoise waters, pure white sand, and vibrant marine life draw hundreds of cruise passengers and daytrippers each year.

Vanuatu is an independent republic in the southwestern Pacific Ocean, consisting of a group of about 70 islands including Espiritu Santo (the largest), Malakula, Efate, Erromango, and Ambrym.
