Viking has added two additional UK sailings this June following positive feedback from clients and has announced plans to run operations in Bermuda and Iceland, again from June.

The move follows the news that the line will restart limited operations from May with domestic cruises on new ship Viking Venus. Initial sailings sold out within a week, the line said.

For the new Bermuda Escape itinerary, Viking Orion will homeport in Hamilton for eight-day roundtrip itineraries, while Viking Sky will homeport in Reykjavik for eight-day Iceland’s Natural Beauty itineraries.

All sailings are for vaccinated guests only. A spokesperson said: “Now that Viking is able to restart operations in other international destinations that have entry rules that require vaccinations for visitors – including Bermuda and Iceland – we have decided to implement a temporary vaccine requirement for guests consistently across our fleet.

“This applies to all scheduled departures at least through to 31 July 2021, including the initial three domestic UK sailings scheduled in May and June 2021.”

Viking said it had been working closely with officials in the UK, Bermuda and Iceland and destinations were chosen because of their “popularity among Viking guests, as well as their commitment to welcoming Viking ships, offering enriching experiences and reviving the travel industry in their respective countries”.

The line is also working on developing sailings in other destinations, including Greece, Turkey and Malta, with the goal of announcing more 2021 sailings as soon as government approvals are given.

Viking chairman Torstein Hagen said: “We applaud the governments of the United Kingdom, Bermuda and Iceland for their collaboration and support in restarting the cruise industry safely.

“No other travel company has implemented the same science-led approach that includes a vaccination requirement for all guests, plus frequent non-invasive saliva PCR testing among all guests and crew.

“Therefore, we believe there will be no safer way to travel the world than on a Viking voyage. We look forward to welcoming guests back on board, and welcoming them back to the world.”
