From February 1st, people travelling to Spain who need to take a Covid-19 test to enter the country will have to get tested within 24 hours before their arrival in the country rather than 48 hours if they choose an antigen test. The rule for PCR tests remains 72 hours.
This currently includes unvaccinated travellers from EU/EEA nations as well as Spanish residents and nationals who haven’t had any Covid-19 vaccine doses, and several third-country categories relating to essential travel. Unvaccinated travellers from the majority of non-EU/EEA countries cannot visit Spain.

If the antigen test has a CE marking, it meets the minimum performance requirements of ≥ 90 percent sensitivity and ≥ 97 percent specificity and has been validated by at least one Member State, it will be accepted by Spanish border authorities.

All international arrivals in Spain also have to fill in a health control form before visiting Spain.
