3 days in Bernese Oberland - Where to stay?

I would make your base in Murren. Transport up and down is very efficient. It allows you to build in some " wiggle room" to wait for clear weather to see the Jungfraujoch. Lots of good hiking from Murren. It is also more fun for your child. Since there are no cars kids can safely explore. In the event of inclement weather there is the community sports center with an indoor pool. http://www.sportzentrum-muerren.ch/en/

Thank you for the reply.

I see that the last cable car to Murren from LB is around 8pm. There is another way to go up but that's not too convenient. Do you think this time restriction will be a problem on the day of Jungfraujoch excursion.

Is the experience at staying on the hilltop way better than staying in the valley? Will spending half a day at the hilltop give me a glimpse of that? I want to experience the best but not at the cost of making it difficult for our parents.

Thanks again,
Komal

There are 2 ways from Lauterbrunnen -> Murren

1) Lauterbrunnen->Stechelberg->Gimmelwald->Murren (latest departure 23:25)
2) Lauterbrunnen->Murren (latest departure 20:35)

Komal, in my opinion staying in Murren is the clear choice. It is not a difficult trip at all. Step off the gondola and onto the small train. Even with my severe arthritis it is easy, so it would be fine for your parents.
The views are something you will never forget, but they can be fleeting because of the weather. If you base yourself in Murren you increase your odds of these superb views as opposed to just spending an afternoon. I don't see a conflict with your trip to the Jungfraujoch because (at least in our experience) that is something you have to do first thing in the morning to improve your chances of having a clear view.
I am not having luck bringing up a Google street view, but here is a link to some images of Murren. https://www.google.com/search?q=street+view+of+murren&client=safari&rls=en&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwjmotST9IjUAhUQ6GMKHdOiB-oQ7AkITw&biw=1171&bih=623
We stayed at the Edelweiss and did half board which included breakfast and dinner. http://www.edelweiss-muerren.ch/en.html?cHash=d1e8f77b350621ba66d6f81b285b68fa

Thank you for the valuable inputs.

What a coincidence, we are also getting one of the apartments offered by Hotel Edelweiss, http://www.edelweiss-muerren.ch/en/appartments/finel.html

I have blocked our stay in an apartment of Hotel Silberhorn, Lauterbrunnen but am seriously going to give Murren a thought now :)

Murren is the best location hands down.

Tim,

I cannot agree more looking at the pictures :)

I am just a bit worried with respect to the time, convenience and luggage since ours is a short trip. But as some of you mentioned, that does not seem to be a lot of a problem.

Though I booked Lauterbrunnen stay just a couple of hours back, I am going to reconsider it now !

Lauterbrunnen is a more convenient location for accessing both sides of the valley, since it's the transportation hub for the area. On your trip to the Jungfraujoch, it will take a bit more time and money if you're staying in Mürren, since you'll have to go through Lauterbrunnen and back.

You appear to have more activities planned in the Mürren / Gimmelwald area so staying Mürren would make sense. You could always visit the Schilthorn instead of the Jungfraujoch, which would make things very easy.

You may want to consider getting one of the Swiss Passes to save some money on the mountain lifts, such as the Half Fare Card or the Berner Oberland Regional pass. You'll have to do the math to determine which pass will work best for your circumstances.

Yes, we will be taking the Swiss Travel Pass. Decided on it after all the calculations :)

About considering schilthorn instread of Jungfraujoch, will there be any chances of snow in schilthorn in August end? Jungfraujoch -our main reason was to experience the snow and one thing off the list kinds :) Is it worth the cost?

There will definitely be snow in on the Jungfrau...

There will not be snow on the Schilthorn in August
