If you do one big trip in your life, this should be it. Silversea Cruises, a Condé Nast Traveler Readers' Choice Award winner, has announced it will be the first-ever company to offer an itinerary that will hit all seven continents. The luxury line's Silversea World Cruise 2020 will stop into 62 ports over 140 days when it sets sail from Fort Lauderdale on January 5, 2020.

Passengers aboard the Silver Whisper, which has a 382-person capacity and is set to undergo a pretty large refurb on the rooms, terraces, and common spaces before sailing around the world, will stop in ports that are both hot on the cruise track and more obscure. They'll dance the tango in Buenos Aires; take in the symphony in Perth while also accessing Australia's remote Pitcairn Island, infamous as the setting of the 18th century "Mutiny on the Bounty"; and visit Vanuatu in the South Pacific, where guests can catch a traditional water dance festival on Champagne Beach. Of the 62 ports, though, the inevitable highlight will be three days spent in Antarctica, where Zodiacs will whip passengers along with nine specialists—marine biologists, ornithologists, geologists—to seal colonies and on glacial expeditions. The itinerary will end in Amsterdam, after a farewell dinner at Edinburgh's famous Mansfield Traquair, like the city's own Sistine Chapel.

Of course, a trip of this type doesn't come on the cheap. Guests can expect to shell out $62,000 a head for a standard cabin, and work their way up to $250,000 depending on cabin class—making it, for now, the most expensive cruising experience on offer. The world's longest cruise, offered by Viking, lasts for 245 days and goes for $93,000 a pop, though you won't see the snows of Mount Erebus in Antarctica from your suite on the Viking Sun on that trip; it goes to 113 ports, but the seventh continent is not one of them.
