Thanks for the question!
As a UK citizen, you only need to have an official photo ID to enter the Republic of Ireland still. Please take a look at our passports page
for all the details. We would suggest also checking with your chosen airline for their terms and conditions.
There is also a lot of positivity regarding changes to the current travel and public health guidelines. To keep up to date as you try to make plans, we'd suggest keeping an eye on our own Traveller's Health
Page for all official resources as there are changes to the public health guidelines
from October 22nd.
Hopefully, this will help, what have you planned to see and do during your time with us?
