We are a group of 4 adults taking the train from Paris to Zurich and want to do day trips via train or car for our first ever trip to Switzerland. We plan on traveling in April and would like to stay in one city (possibly two cities at most). We know we won't be able to see a lot of cities in five days, but the cities we are most interested in is Bern, Interlaken, Lucerne, Zurich, Basel. We would also love to see the Rhine Falls, but is it worth it? Doing some research, it seems Zurich or Lucerne is the most central for the cities, but we do have to be back to Zurich to catch a train to Italy, so we'll need to be back to Zurich at some point. We are not a group that does a lot of hiking, we mostly enjoy the scenery, the culture and the food. Any advice or recommendation on itinerary and base for 5 nights/6 days?
Thanks in advance!
