Lindblad Expeditions will resume operations in June with sailings in Alaska and Galapagos.

The small-ship expedition cruises will require proof of Covid-19 vaccination for all guests aged 16 and above, plus two negative Covid tests before boarding.

There will also be daily guest temperature checks and thorough sanitation protocols.

Sven Lindblad, chief executive of the cruise and adventure travel company, said: “Our internal team has spent the last year examining every single aspect of our operation to be prepared to operate in the ‘new normal.’

“Led by our resident medical expert, Dr David Lorber, we have enlisted the assistance of many health and safety experts and met with authorities in the regions we intend to explore to ensure we are welcome and meet or exceed their expectations.”

The Alaska cruises will offer six and eight-day itineraries on 100-passenger sister ships National Geographic Quest and National Geographic Venture, with the first departures June on June 5 and June 6.

The Galapagos cruise will be a 10-day itinerary on the 96-passenger National Geographic Endeavour ll, with the first departure on June 4.

• The company has also appointed Dolf Berle as president and chief executive, effective from May 10.

He succeeds Lindblad, who will become co-chair of the board, together with Mark Ein, current board chair.

Berle is currently chief executive of Topgolf Entertainment Group.

Lindblad has been chief executive since founding the company in 1979.
