Montenegro, an enchanting country on the Adriatic Sea, is known for its breathtaking coastline, historic towns and hospitable people. Those who have fallen in love with this pearl of the Balkans often ask themselves the question: How long can I stay in Montenegro without a residence permit? This question is particularly relevant for travelers from the European Union (EU) and beyond, as there are different entry requirements depending on whether you enter the country with an identity card or a passport.
