Spain have good news from tourists from EU.
Tourists from within the EU or Schengen area no longer need to show any COVID-19 documents in order to enter the Spain. Visitors from outside the EU however, still need to show proof of vaccination, recovery certificate or a negative test through the EU Digital COVID Certificate (EUDCC) or another valid document.
If you don’t have the certificate (or another EU equivalent) you can fill in Spain’s Health Control Form with these details, receiving a QR code to get through the airports.
Either a PCR or rapid antigen test – taken within 72 or 48 hours before arrival, respectively – are accepted.
