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.
Choice 1: The "Grand Alpine Scenic" Route (Best for Scenic Trains)
This route uses the UNESCO-listed Bernina Express and visits the most iconic mountain peaks.
- Day 1: Milan to St. Moritz via the Bernina Express
- Take a morning train from Milan Centrale to Tirano (2.5 hours).
- Board the Bernina Express in Tirano. This 4-hour journey crosses the Alps, reaching glaciers and high mountain lakes.
- Stay: St. Moritz.
- Day 2: St. Moritz to Zermatt via the Glacier Express
- Board the Glacier Express, known as the "slowest express train in the world," for a full day of panoramic Alpine views.
- Arrive in Zermatt, a car-free village at the foot of the Matterhorn.
- Stay: Zermatt.
- Day 3: Zermatt & Return to Italy
- Take the Gornergrat cogwheel train for the best view of the Matterhorn.
- Return to Italy via the Simplon Pass (Zermatt > Brig > Milan) in about 3.5 hours.
Choice 2: The "Lakes & Swiss Heritage" Route (Best for City Lovers)
This route focuses on charming cities and traditional Swiss culture, entering through the Italian-speaking Ticino region.
- Day 1: Milan to Lugano & Lucerne
- Take a direct EuroCity train from Milan to Lugano (60-90 mins). Explore the lakeside promenade.
- Continue through the Gotthard Base Tunnel to Lucerne (2 hours).
- Stay: Lucerne.
- Day 2: Mt. Pilatus or Mt. Titlis
- Spend the day on a mountain excursion. Mt. Pilatus (via the steepest cogwheel railway) or Mt. Titlis (glacier views and cave) are accessible from Lucerne.
- In the evening, stroll across Lucerne’s iconic Chapel Bridge.
- Stay: Lucerne.
- Day 3: Interlaken & Return
- Take the Luzern-Interlaken Express (panoramic views of 5 lakes) to Interlaken.
- Explore Brienz or take a short cruise on the turquoise water.
- Return to Milan via Spiez and Brig (approx. 3 hours).
Practical Tips for 3 Days
- Main Hub: All major Swiss routes connect most efficiently through Milan Centrale. If you are starting in Venice or Florence, you will likely need to transit through Milan first.
- Swiss Travel Pass: For a 3-day trip involving multiple long train legs and mountain excursions, a 3-day Swiss Travel Pass is invaluable. It covers all trains, boats, and most public transport, and offers 50% off most mountain cable cars.
- Booking Scenic Trains: The Bernina Express and Glacier Express require advanced seat reservations, even if you have a rail pass. Book these at least 2–3 months in advance during peak season.
- Luggage: Trains in both Italy and Switzerland have ample space for luggage, but for 3 days, traveling light is advised as you will be changing hotels frequently.
