“If you cannot fulfil the entry requirements, you will be required to return to your country of origin.”
Restrictions also apply to those arriving by water.
The FCO stated: “Cruise ships can berth at ports on mainland Portugal, but passengers can only disembark if they are Portuguese nationals or residents.
“Recreational vessels and private yachts are still not permitted to dock, except for refuelling or taking on supplies.
“Passengers may only disembark to return to their country of origin and once they have completed 14 days’ self-quarantine on board, starting from the day the vessel entered Portuguese territorial waters.
“Cruise ships are allowed to dock in Madeira and Porto Santo for a maximum period of 48 hours, but passengers and crew are not allowed to embark or disembark.
