After disruptions to night train services between Paris and Berlin, European Sleeper will launch its own service starting in March 2026. Trains will depart from Paris on Tuesday, Thursday, and Sunday evenings, with returns from Berlin the following days. For a cozy and scenic journey, consider checking out the new route this summer; Berlin’s mild weather in June means you can explore its vibrant cityscape comfortably—expect cloudy skies but pleasant temperatures around +16°C.
