Swiss Nomad -
Yours was another very helpful reply. Thanks very much!!!
"It will help a lot to look at a map while reading the advice here. You can also use the Swiss train website to check travel times between places. sbb.ch"
Good advice. I found a map showing the trains, and printed it.
"Zermatt is a wonderful destination, but it sits at the end of a narrow valley and is reached by a single train line (look at Visp - Zermatt on SBB. it is about an hour in/out). Because of this, every day trip requires traveling down the same route and back again just to get in and out of the valley. This adds two hours to any possible day trip destination."
Good thinking! I was not aware of this. I see from the map that Wengen, Grindelwald, Interlaken, all appear easily accessible to each other and quite centrally located, while Zermatt is quite far south, practically in the Italian Alps. So, yes, we we will leave Zermatt out of the plan.
"It sounds like you want to see several places, that is why Wanderweg suggested Wengen as a base and provided a possible itinerary for your time there. If you look at Wengen on a map, you will see it is very close to Grindelwald and Interlaken. There are many activities in this area, which makes Wengen a much better base for a five-day stay over Zermatt. In your second post you listed Mürren and Zermatt together, but they are quite far apart, so I would remove Zermatt from this plan.
I would also remove: Stoos – too far away, and the hike is more difficult than what you described enjoying. Trift Bridge – also takes quite a bit of time to reach."
This is extremely helpful guidance! I see that now and I understand why this is being advised.
Now, to get to Wengen... Some information I looked up online says it takes 7-11 hours and 3-6 train changes to get to Wengen from Venice, while some people have told me it takes 6-8 hours. Some people in this thread suggest we fly from Venice to Zurich and then take a train, while others disagree.
Now that I am almost settled on Wengen as our home base in Switzerland, the best way to get there from Venice is the big question. I looked at a train ticket site and compared several options. It appears that flying is more expensive and won't save much time, plus we'll still have to add train(s) after the flight. If we can get a direct flight, that is a bit over an hour, but of course we'd need to arrive early for customs/security and lines and then take train(s) from the airport to Wengen.
"You will find the remaining places on your list, and more, in Wanderweg’s suggested itinerary.
If you want to walk around Interlaken, that is easy to add. You will pass through it anyway on the way to Brienz or if you take a boat on the lake."
Great! That also gives us a change to have some flexibility for weather. If we use Wengen as our primary place to stay, and make day trips to Gridelwald and other places, do you think there is any need to move to any other places to stay, or can we do most of our list (except those you explained are too far off) from our hotel or VRBO/Air B&B in Wengen?
"For your flight from Zürich:
If it leaves later in the day, travel from Wengen that morning. Check SBB: Wengen - Zürich Flughafen for travel times.
If it is early in the day, travel to Zürich already the night before."
Others have also suggested flying out of Bern. What do you think of that if we do make Wengen our base?
