Hello all! I’ve done some research here and elsewhere, combined with our personal checklist and came up with the below itinerary
1 Arrive Zurich 1PM, train to Bern (Sleep Bern)
2 Train to Zermatt (Sleep Zermatt)
3 Matterhorn/Zermatt (Sleep Zermatt)
4 Train to Lausanne or Montreux (Sleep Lausanne or Montreux)
5 Montreux/Lausanne/Geneva (Sleep Lausanne or Montreux)
6 Train to Lauterbrunnen Valley (Sleep Murren)
7 Lauterbrunnen Valley (Sleep Muren)
8 Lauterbrunnen Valley (Sleep Murren)
9 Train to Lucerne (Sleep Lucerne)
10 Lucerne (Sleep Lucerene)
11 Train to Airport, Fly home
Using sbb.ch, I made a chart of estimated train times to and from each base. The only leg I wanted to dictate was Montreux to Interlaken, so that we could take those two legs of the Golden Pass route. This itinerary had the least amount of time on trains of the others I came up with, so I think it will work nicely.
Day 4 and 5 are still being researched and planned, so could stay in either place. Don’t want to put too much in the 1.5 days we'll be in that area. If anyone has advice on how best to spend the time in that area, I'd love to hear it. I suppose another option would be a third night in Zermatt to maximize chances of good weather for Matterhorn, but is there enough to do in that area to justify that while taking time away from elsewhere?
Any other comments on this new itinerary are very welcome. Have a great day!
