Spain is now among the countries with the highest Covid-19 rates in Europe as an army of Irish tourists get ready to head there next week.
International travel will be unlocked in Ireland come Monday as the EU Covid Digital Green Cert begins.
But tourists are being warned that the Delta variant has surged in Spain in recent weeks and has been described by the Health Minister as "very bad".
Barcelona reintroduced a curfew earlier this week while a night-time curfew was also approved on Monday in the neighbouring region of Valencia, while Navarre, which also borders Catalonia, presented the same request to its Superior Court of Justice earlier this week.
In Catalonia all bars, restaurants and cultural venues must now close at 12:30 a.m. and eating and drinking in the streets is banned.
The Balearic Islands, which includes Mallorca and Ibiza, have also had to reintroduce curfews to stop the spread of the virus.

The Canary Islands is also struggling with a surge in Covid as some restrictions are imposed to stop the spread.
Earlier this week the Spanish government updated a list of entry requirements for Irish people wishing to holiday in Spain.
From earlier this week, a negative PCR test or PCR-like test (NAAT type) can be issued within 72 hours before arrival in Spain.
Previously PCR tests had to be taken 48 hours before arrival but this has been extended.
Irish tourists must also show their Health Control Form (FCS). This form must be completed and signed electronically before you arrive in Spain by air or sea.
You can access the form and sign it via the Spain Travel Health website or apps for Android and iOs users.
