Swimming with blue whales (Weligama, Sri Lanka)

Manta rays and whale sharks are so 20th century.

The real catch for divers today is the blue whale, the heaviest animals that ever lived, and the best way to experience a close encounter is to sign up for a trip with an expert.

Natural World Safaris' eight-night, once-in-a-lifetime package was created by Patrick Dykstra, one of the first people to photograph and interact with Sri Lanka's blue whales.

Your base is Weligama Bay on Sri Lanka's southern coast, also the departure point for daily whale-spotting excursions, during which you'll have the chance to swim with, photograph or simply watch the mysterious giants.

Luxury island-hopping (Similan Islands, Thailand)

If one sun-drenched, sand-covered paradise isle isn't enough, you can sign up for a luxury six-night island-hopping experience.

There are no budget hotels or dodgy bus journeys.

Instead, you'll spend three nights at the Phulay Bay Ritz-Carlton Reserve and three nights on the luxury yacht that will take you on a three-night tour of the beautiful Similan Islands.

Tour of North Korea

There are fairly frequent tours to North Korea these days, but it's still one of the world's most secretive states.

An 11-night visit here gets you the attention of the dinner table for a good few weeks.

"The constant stream of military personnel and statues of the Kims are fascinating, but what really blew me away was the scenery," says Paul Murphy, who visited in 2012.

"Obviously visitors are very closely monitored, but I was surprised by how beautiful the mountainous areas are, and there are also some stunning lakes."

250K package, Hyde Bellagio (Las Vegas)

For $250,000 (loose change to the average poker champ), guests at the Hyde Bellagio nightclub in Las Vegas can sign up for a package that gets them seated centerstage on the Bellagio's patio before being given a 30-liter bottle of champagne and a special gold box.
