Spain to Denmark visa requirements

No visa. Spain and Denmark are both EU member states, so a Spanish citizen has full EU free-movement rights and can enter Denmark for tourism with just a valid Spanish passport or national ID card, with no stay limit. Spain and Denmark are both members of the European Union and the Schengen Area. As an EU citizen, a Spanish ordinary passport holder enjoys the right to free movement: no visa is required to travel to Denmark, and travel is permitted with either a valid Spanish passport or a Spanish national identity card. The Schengen 90/180-day short-stay limit applies only to non-EU nationals, so a Spanish citizen faces no time restriction on tourist or short visits and may stay, work, or study in Denmark. ETIAS, the upcoming EU travel authorisation for visa-exempt non-EU nationals, does NOT apply to EU citizens such as Spaniards. Because Denmark is internal to the Schengen Area, there are normally no systematic passport checks when arriving from another Schengen country (e.g. Spain), though carrying a valid ID document is still legally required and some airlines demand a passport for boarding. Denmark may temporarily reintroduce internal border checks in exceptional circumstances, in which case identity must be proven on request.
