Citizens of non-EU countries, including those who hold blue Gibraltar residence cards, are being refused entry to Spain unless they provide evidence of travel and hotel reservations.
For those transiting through Spain, it is something to be aware of.
Spanish border guards began to carry out stricter checks on people from mid-March, even refusing entry from Gibraltar to Spain for many non-Gibraltarians.
Evidence of onward travel and accommodation reservations in Spain, or elsewhere, are being demanded from any non-EU national, including British passport holders, before allowing people to cross the Spanish border.
These more stringent Schengen entry controls do not seem to apply to third country nationals who are officially resident in Spain, or to Gibraltarians with red residence cards.
