Yes, you can absolutely leave Amsterdam Airport Schiphol (AMS) during an international layover, provided you meet the entry requirements for the Netherlands. For most travelers in 2026, this requires a valid passport and, for certain nationalities, a Schengen Visa or an ETIAS authorization. Schiphol is one of the most convenient airports in the world for a quick city visit because the train station is located directly beneath the terminal. A train ride to Amsterdam Centraal takes only 15 to 20 minutes, with trains running every few minutes. If you have a layover of at least 5 to 6 hours, you have enough time to take the train into the city, enjoy a canal cruise, eat some Dutch fries or a stroopwafel, and return to the airport. However, you must factor in the time needed to clear passport control (which can be slow) and re-clear security upon your return. Schiphol also offers a secure baggage storage area where you can leave your carry-on bags. It is a highly recommended way to break up a long journey, as the efficiency of the Dutch rail link makes Amsterdam one of the most "explorable" cities for transit passengers in Europe.
