Bermuda is among 22 countries that require fully vaccinated people to take Covid-19 tests to visit, a travel agency website showed.

A restrictions map on Kayak indicated that another four countries required testing as well as quarantine but 183 were open for travel without either and 18 were “closed“.

The figures were based on fully vaccinated travellers departing from the United States — where most of the island’s visitors come from.

A travel authorisation form with a $40 fee must be completed and the application must be approved before people can travel to Bermuda.

The Government website said that vaccine and testing requirements depended on residency and method of arrival to the island.

Kayak showed that 70 countries — including Bermuda — required testing when travellers were not fully vaccinated.

The number of open countries dropped to 104 in that case, with 16 countries listed as “test and quarantine”.

A total of 37 countries — including the US — were said to be closed to travellers who were not fully vaccinated, meaning that only returning citizens or people in special circumstances could enter.

Data from the Bermuda Tourism Authority showed that in 2021 passengers from the US accounted for 94 per cent of all cruise arrivals in Bermuda and 80 per cent of air visitors.

The comparable figures from 2019, before the coronavirus pandemic, were 87 per cent and about 75 per cent.

Bermuda’s testing requirements were blamed this week for the cancellation of trips to the island by two cruise lines.

It was revealed on Wednesday that Celebrity Cruises pulled four stops to Bermuda that were scheduled for later this year.

An official notice of the cancellations, confirmed by an industry source familiar with the procedure, said that owing to “Bermuda’s current testing requirements, the cruise lines have decided to cancel the following upcoming (transatlantic/repositioning) call to Bermuda”.

Norwegian Cruise Line cut three visits.

It was understood they included Norwegian Escape, which was due to call at Dockyard on November 15 and would mark the biggest-capacity loss to the island with a maximum passenger capacity of 5,218.
