Start in Zurich for a seamless ride on the Luzern–Engelberg Express, changing directly beside platform bakeries fragrant with butter croissants. Check into a guesthouse steps from the funicular, rent snowshoes, and circle a frozen lake before fondue. The return day fits a spa soak and panoramic gondola with timed trains that make departures stress‑free. Reserve seats, screenshot timetables, and travel light; you’ll never miss the car.
Fly to Tromsø or Narvik, then lean on airport buses, local shuttles, and a short fjord ferry to reach dark-sky viewpoints safely. Bundle merino layers, carry microspikes for icy sidewalks, and book a guided aurora chase that includes coach transport. If clouds linger, swap plans for a waterside sauna, museum, or bakery crawl. Your biggest decision becomes cinnamon roll or cardamom bun, not studded tires versus chains.
String Vienna, Bratislava, and Budapest with hourly rail links that feel like moving living rooms. Drop bags at station-adjacent hotels, ride trams into illuminated squares, and follow the scent of roasted chestnuts between stalls. Reusable mug in hand, taste regional specialties without navigating traffic. Morning departures are calm, seats plentiful, and reservations optional. If snowflakes arrive, they fall romantically across windows while your itinerary hums along on time.
