Visa Requirements
British citizens don't need a visa to travel to Portugal if travelling for under 90 days within a six-month period.
Passport Validity for Portugal Travel
Your passport should be less than 10 years old (as shown by the 'date of issue') when you enter the country, and its expiration date should extend at least 3 months beyond your planned departure.
Other Key Entry Information
Portugal uses the EU's Entry/Exit System (EES), so you may need to register your biometric details (such as fingerprints and a photo) on arrival.
