Yes, Monaco is included in the Interrail Global Pass in 2026. While Monaco is a sovereign city-state, its only railway station—Monaco-Monte Carlo—is operated by the French national railway, SNCF. Therefore, your Interrail pass works exactly as it would in France. You can take the regional TER trains from Nice or Ventimiglia directly into the heart of the Principality without needing any additional reservation. However, if you are traveling on a high-speed TGV or an international Thello train to reach Monaco, you will still be required to pay the standard seat reservation fee associated with those specific services. For 2026 travelers, using an Interrail pass is one of the most cost-effective ways to visit Monaco, allowing you to stay in more affordable nearby French towns like Villefranche-sur-Mer and "commute" into the luxury of Monte Carlo for the day with just a simple tap of your digital pass.
