Suggest an itinerary with Ringgenberg as base

I had booked and made an itinerary based on Luzern. The airbnb cancelled 3 days back. Saw a good deal in Ringgenberg in bookingdotcom. Booked without even thinking as we have only a few days.

We will arrive at 7.30 Am on May 11 th -Zurich. We have already booked our stay at Ringgenberg and will be leaving to Paris at 1 pm on May 11

Sounds like you are leaving for Paris as soon as you arrive in Zurich. Take it you are really arriving on May 6.

Sorry, we are leaving for paris on 16 th

Most of the chocolate factories are in western Switzerland, or around Zurich. Maybe this place in Interlaken will suffice.

For the rest, play it by ear depending on the weather.

Or Schilthorn

This is what I am currently working on

If by Bernier Express, you are referring to the Bernina Express, that is too far away to be considered.
If you are getting the Berner Oberland Pass, Mt Rigi is not included, but Engelberg and Titlis are half fare from Luzern (which is included). If you want a scenic train journey, take the Golden pass train toward Montreux, It is fully covered to Saanen, then half fare to Montreux. Other mountain top journeys close to Ringgenberg are the Brienzer Rothorn, the Schynige Platte, Harder Kulm, Niederhorn.

Again, shape your itinerary by the weather. Bern day trip would be a good rainy day activity. Take advantage of good weather to go into the mountains when it is favorable. With a pass, you are not locked into doing anything on any particular day.

Brienzer Rothorn and Schynige Platt is closed in may, is it?.
Should I book a seat for the Golden express

For 4.5 days, weather dependent….

Thanks Wanderweg.
Thanks. I will work based on this plan and get back with my doubts.

Day 1
11/5/2024
Arrive in Zurich at 7.30 AM. Travel to Ringgenberg. Check in.
After lunch Berne. Old Town,Cathedral,Zytglogge,Bear pit. ?zoo
Berne to Interlaken Cruise
Return to Ringgenberg

Day 2
12/5/24
If the weather is good –Jungfraujoch
Is the stay at the hut on top worth it?
Can children hike up to the hut? We all have snow boots and -10 Jackets. None of us have seen snow, not even a temperature less than 20.
If not going to the hut – then on the return walk murren Grütschalp
(to get to murren would be Grindelwald- Lauterbrunnen – by bus Stechelberg – Murren am I right? as Grindelwald Murren line is closed))
Will that be too much for the day ?

Day 3
Morning Grindelwald First
Afternoon Lauterbrunnen, Trummelbach Falls
?Wengen too in the evening

Day 4.
Oeschinen Lake
THUN Castle
Harder Kulm or Neisen or Stockhorn
Day 5

Explore Lucern

Evening Chocolate factory at Interlaken for Kids

Can you please have a look at this itinerary and suggest edits.

Day 1 - if you want to see Bern on the way to Ringgenberg, stop and store your luggage there on the way. Don’t backtrack. And there is no such thing as a Bern to Interlaken cruise, there is just a train. You can take a boat from Interlaken to Ringgenberg though, on Lake Brienz. You can do Harder Kulm for sunset if you want.

Day 2

Jungfraujoch + Murren is too much in one day, but you can do Jungfraujoch + Grindelwald First this day. Take the Eiger Express down to Grindelwald after Jungfraujoch and do First in the afternoon.

Day 3

Ringgenberg > Bus to Interlaken Ost > Lauterbrunnen > Walk to Stechelberg > Cable car to Gimmelwald & Murren > Cable car back down to Stechelberg and Bus to Trummelbach Falls > Bus to Lauterbrunnen > possibly up to Wengen for dinner > back to Lauterbrunnen > Train to Interlaken Ost > Bus to Ringgenberg

Day 4.

Oeschinensee is a lot of logistics and I wouldn’t recommend unless you really want to spend your whole day doing it. A boat ride on Lake Thun + Thun castle would be nice.

Day 5

Luzern
