In order that you are informed about all the requirements and restrictions on COVID-19 throughout Catalonia, I highly recommend you check very well the following official links that are constantly updated:
- Catalan Tourist Board: Updated information on COVID-19 and trips to Catalonia
- Generalitat de Catalunya, Territorial Measures and Restrictions: Restrictions throughout Catalonia (COVID-19)
- Spain Travel Health portal
Moreover, I suggest you always book travel insurance when travelling.
Please, also be aware of the cancellation policies of your hotel, transportation and activities reservations. No one wants to have a surprise if something happens.
And we all know that things happen!
