A 3-day trip to Switzerland from Italy is most efficient when starting from Milan, the primary gateway for high-speed and scenic trains. For a short stay, focusing on either the Bernina Express route (best for scenery) or the Ticino to Lucerne axis (best for cities and lakes) is recommended.
This route uses the UNESCO-listed Bernina Express and visits the most iconic mountain peaks.
This route focuses on charming cities and traditional Swiss culture, entering through the Italian-speaking Ticino region.
