The Foreign Office has warned Brits ‘against all but essential travel’ to Spain.
It took the decision after a spike in coronavirus cases in several Spanish regions including Aragon, Navarra and Catalonia.
The government department’s official website says the designation was based on an assessment of ‘Covid-19 risks’.
However, the Canary and Balearic islands are exempt from the travel advice, although Brits who visit the islands will still have to quarantine when they return.
The Foreign & Commonwealth Office (FCO) website states: “From 26 July, the FCO advises against all non-essential travel to mainland Spain based on the current assessment of Covid-19 risks.
“Only the Canary Islands (Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, El Hierro and La Graciosa) and Balearic Islands (Mallorca, Menorca, Ibiza, and Formentera) are exempt from the FCO advice against all non-essential international travel.
“This advice is based on evidence of increases in cases of Covid-19 in several regions, but particularly in Aragon, Navarra and Catalonia (which include the cities of Zaragoza, Pamplona and Barcelona).
“The FCO is not advising those already travelling in Spain to leave at this time.”
The Foreign Office has advised Brits in Spain to follow the advice of local authorities.
It added: “If you are returning from Spain on or after 26 July you will be required to quarantine on your return to the UK, but the FCO is not advising you to cut short your visit. You should contact your tour operator or airline if you have any questions about your return journey.
“PHE are continuing to monitor the situation in the Balearic and Canary Islands closely. Travellers there should continue to check this advice regularly.”
Brits will not be required to self-isolate when they arrive in Spain, although they will have to provide the Spanish Ministry of Health with contact information and any history of exposure to coronavirus 48 hours prior to travel.
They will also have to undergo a temperature check and a visual health assessment.
