7. Saba, Dutch Caribbean
Known as the "Unspoiled Queen," Saba, in a rather ironic twist, is a favorite with the LGBT community.
Same-sex marriage is legal here and its commissioner and director of tourism are openly gay.
With 1,800 residents, four villages and only a small harbor, the volcanic island (Mount Scenery is still capable of erupting) near St. Martin is the smallest municipality of the Netherlands and the only one that speaks English and uses the American dollar as its official currency.
Saba has the shortest commercial runway in the world and its one main road, built nine years before there was even a car, was masterminded by a local who defied Dutch and Swiss engineers who said it couldn't be done. Josephus Lambert Hassell started building in 1938 with five friends after taking a correspondence course in engineering.
8. Quilalea, Mozambique
This 86-acre private island sits in the middle of a protected Indian Ocean marine sanctuary.
Until 2011, when Christopher and Stella Bettany built nine coral and thatch villas, its only residents were nesting sea turtles and a sizable menagerie of wildlife.
Azura at Quilalea eco-resort offers a clifftop spa, a trail leading to dense baobab groves and sailing trips on traditional Mozambican dhows.
Azura at Quilalea; +27 (11) 791 0519; $25,000 per night for the whole island
9. XXXX Island, Australia
Man caves out. Man islands in.
The reason XXXX island is little known is because it's still in diapers.
It was only hatched a year or so ago when beverage company Lion, which owns the XXXX Gold brand, leased the 15-acre property, acquired naming rights (the island used to be called Pumpkin Island) and started holding promotional competitions.
The island is now the ultimate beer paradise, with a pool table, darts, a golf course (OK, it has one hole), Xbox room, rods and tackle, a bar showing nonstop sports and huts with names like The Locker Room and the House of Rock.
You can't rent those huts, but you can win vacations here along with three of your closest buddies.
Contest winners started showing up in late 2012 for coming up with such creative schemes as beer butlers, football goals set in the ocean, a spray sunscreen booth, tree houses with fireman poles and a "loo with a view," a glassed-in bathroom overlooking the ocean.
Off the Capricorn Coast, Great Barrier Reef, Australia; free if you win one of many contests sponsored by XXXX Island
10. Guana Island, British Virgin Islands
