Citizens of the European Union, Iceland, Liechtenstein, Norway, and Switzerland and family members
Citizens of the Member States of the European Union, and citizens of Iceland, Liechtenstein, Norway, and Switzerland, may enter Spain with their national identity card or with a valid passport. Minors who travel with an identity document and are not accompanied by a parent will need the authorization of one of their parents.
Family members who are not nationals of a Member State of the European Union or of Iceland, Liechtenstein, Norway, or Switzerland may enter with a valid passport. Depending on their nationality, they may need an entry visa, unless they have a valid residence card as the relative of a European Union citizen.
If you do not belong to the previous group, you might need a visa to enter Spain.
