Yes, you can travel to Europe with a UK travel document (such as a British Passport), but for 2026, there are significant new requirements to keep in mind. Following the full implementation of the ETIAS (European Travel Information and Authorisation System), most British citizens now need to apply for this travel authorization online before visiting any of the 30 countries in the Schengen Area. The ETIAS costs €7 for adults (free for those under 18 or over 70) and is electronically linked to your passport for three years. Your passport must be a biometric (chip-enabled) version and have at least three months of validity remaining beyond your intended date of departure from Europe. You must also adhere to the 90/180-day rule, which permits you to stay in the Schengen Zone for a maximum of 90 days within any rolling 180-day period. These rules apply whether you are traveling by air, sea, or via the Eurostar train from St Pancras, ensuring that your border crossing remains smooth and compliant with modern EU security standards.
