UK passport holders traveling as tourists do not require a visa for short stays in EU destinations, provided the trip falls within the 90-day limit per 180-day period.
Importantly though, please make sure you have at least 3 months validity on your passport at the time of travelling (although it is advised to have 6 months if travelling to Europe) and be able to show at border control a return or onward ticket and that you have enough money for your stay.
If you are not a citizen of a country in the Schengen area, you can check this here, you may be required to obtain a Schengen VISA to travel to your holiday destination,
Please see the below link to find out more:
The Schengen Area covers most of the European Countries. A Schengen visa is a short-stay visa that allows a person to travel to any members of the Schengen Area, per stays up to 90 days for tourism or business purposes.
The Schengen visa is the most common visa for Europe. It enables its holder to enter, freely travel within, and leave the Schengen zone from any of the Schengen member countries. There are no border controls within the Schengen Zone.
We would recommend applying for your VISA as soon as you confirm your NUCO booking as it can take some time to arrange an interview with the relevant embassy.
