Tetiaroa, French Polynesia
Strictly speaking, Tetiaroa isn't just one single island, but rather an atoll of 13 islands surrounded by a coral reef in French Polynesia, about 30 miles (48.2 kilometers) north of Tahiti [source: Pacific Island Travel]. Actor Marlon Brando fell in love with the islands while filming "Mutiny on the Bounty" in and around Tahiti and bought them for about $200,000 in 1965 [source: Maxim].
The reason for his attraction is easy to see: With a total area of about 1,433 acres (580 hectares), the islands are a green oasis in a turquoise blue sea, complete with calm waters, palm trees and (do we even have to say it?) white sand beaches [source: Private Islands]. After Brando's death in 2004, a developer purchased the land for $2 million with plans to open a luxury eco-hotel in late 2011 [source: Private Islands].
