Entry Requirements for Portugal
Visa Requirements
British citizens don't need a visa to travel to Portugal, provided their stay is under 90 days within a six-month period.
Passport Guidelines
Your passport needs to be valid for the duration of your stay, especially for trips lasting up to three months. Keep in mind that your passport should be less than 10 years old from the 'date of issue' upon entry, with an expiration date extending at least 3 months beyond your planned departure. For more detailed information, you can contact the country's embassy in the UK.
