For international travellers, a passport is indeed required to enter Amsterdam. This includes visitors from the UK, who, following Brexit, must now present a valid passport upon arrival.
The Passenger Terminal Amsterdam serves as the primary entry point for many visitors, including those arriving on Amsterdam cruises. It's important to ensure that your passport is valid for at least 6 months beyond your planned stay. This requirement is a standard entry condition for many countries and ensures a smooth passage through customs and immigration.
