Travel tips- First time Visit

Go to the Jungfraujoch only if the weather is clear. This could be on your arrival day or Day 2 or 3. Even with Swiss Travel Passes, you only get a 25% discount above Wengen, so it will be about 150 CHF per person.

It will be "brisk" on the Jungfraujoch. Have some warm layers, not necessarily winter clothes.

If you have Swiss Travel Passes, Rigi is free.

Yes, layer for the Jungfrau. It will be a lot cooler up there.

We’ve been in Switzerland four times on August 1, Prahains, Zug, Zermatt and Bern. With the exception of the village where we were staying the first time, restaurants in the cities were open and food was readily available at the festival sites. This summer we are staying near Lake Geneva in a French town but plan to spend the day in Switzerland to enjoy the celebration and fireworks on August 1. Where will you be in Switzerland on August 1?

We visited Mount Titlis in July a few years ago. Short sleeve shirts and capris were fine in Engelberg, and we each put on windbreakers or fleeces once we got to the snowy mountain top. The snow was pretty slushy in parts. It was spectacularly beautiful, and not bitterly cold. Maybe that perception had to do with us being from Michigan? It was a very memorable day. One of the lasting memories beyond the beautiful landscape was seeing people from warmer climates experiencing snow for literally the first time in their lives. We stayed in Engelberg for two nights, hoping that one of the days would have desirable weather to go to the top of the mountain.

On the way back down from the top of Mount Titlis, we got off the gondola in the town of Trubsee. From there, we walked a short distance down to a beautiful lake, and actually were part of a cow parade as the farmer was bringing his cows back to his farm. That was an unexpected and melodious bonus. My son even rowed me around the lake in a rowboat when we were there. It was truly beautiful. Then we just walked back up to the lift station and caught the next gondola down to Engelberg. Highly recommend. :-)

Your time is short. Travel time may cut into how much you can see. All of Jungfraujoch can be seen in one day from Interlaken. We even hit Lauterbrunnen/Murren in the afternoon. Up on the Eiger Express and down on the train to Wengen.

YouTube videos helped me identify and prioritize the attractions most interesting to me. The AI narrated videos were not helpful. I can provide some contributors that helped me plan two trips so far.

@mona we should be in
lucerne area for Aug1st

For such a short trip, I think you need to condense a bit of your lodging changes and allow buffer for weather and enjoyment of the area. I'd suggest something more like this (Wengen 3 nights/Luzern 2 nights):

Day 1 - Zurich > Wengen - depending on your arrival time, perhaps go up to Mannlichen/Royal Walk for great views - the kids will love the playground and the adults will love the views

Day2 - Wengen > Jungfraujoch (if some people in your group like walking/easy hiking - then they can go up to Mannlichen and do the walk from there to Kleine Scheidegg, while others can train to Kleine Scheidegg and you can all meet up to go up to Jungfraujoch)

Day 3 - Wengen > Lauterbrunnen > Murren > optional Schilthorn, visit Gimmelwald, etc. - many great options over here

Day 4 - Wengen > Luzern - explore, Chapel Bridge, Lion Monument, etc.

Day 5 - Luzern, optional day trip to Zurich for a city tour if that really interests you, or day trip to Bern or up to Mt. Rigi

Day 6 - Luzern > Zurich airport
