We're a family 3 - 2 adults and a 3 months old baby, landing in Geneva at the 30th of June and taking a train straight away to Wengen.
We'd be staying in Wengen for 4 nights, returning to Geneva by train for an extra night and flying back home.
We plan to take day trips from Wengen to Interlaken, Grindelwald and maybe Zermatt (if we won't go to Interlaken or Grindelwald), and we don't plan to reach high altitudes (which are not recommended for babies).
Overall, we plan to use public transportation for 4 days out of our 6 days in Switzerland, including the way from and back to the Geneva's international airport.
So our question, is which Swiss pass will best fit our need, and what will be its costs?
Appreciate your help!
