Viking Cruises reveals details of what will be the longest cruise journey ever

It would take someone who really loves holidaying on the high seas — and who has a lot of annual leave up their sleeve — to take on this epic cruise.

Viking Cruises has revealed details of what will be the longest cruise in history: a continuous, eight-month journey that takes in 59 countries and 113 ports in every continent of the globe — except for Antarctica.

With 930 passengers on board, the Viking Sun will leave London on August 31, 2019 and circumnavigate the globe for a marathon 245 days, including 22 overnight calls, news.com.au reports.

Heading west from London, the ship will work its way around Great Britain and then call into Iceland, Greenland and Canada, before heading along the east coast of the United States, the Caribbean and around South America.

Then, the Viking Sun will cross the Pacific and reach New Zealand, which includes stops at Auckland and Dunedin. It will then hit up a pretty big variety of Australian destinations, including Thursday Island, Cairns, Whitsundays, Brisbane, Sydney, Melbourne and Hobart.

It then moves up through Asia, over to the Middle East and northern Africa, through the Mediterranean, and back to London on May 2, 2020.

The voyage is almost twice as long as Viking's 2017 world cruise, which was a comparatively brief 141 days (four and a half months).

And it doesn't come cheap.

Prices start at $126,718 for a "Veranda" room and go all the way up to $368,246 for the exclusive "Owner's Suite" — which has already sold out.

But willing passengers will get plenty of bang for their buck.

As well as getting to visit about a third of the world's countries in a single trip, passengers can enjoy perks, including unlimited Wi-Fi, a 7500-litre infinity pool and a Nordic spa with a "snow grotto".

They can also benefit from the ship's resident historian, who will offer lectures on art, history and other subjects that correspond to the next destination.
