Inn to Inn hiking in Bernese Oberland

Switzerland has a great luggage forwarding system provided by the SBB. It makes such a trip quite reasonable, because if you plan it right you only need to carry 2 days of luggage with you, so a fairly light pack.
Cannot advise on whether these hikes are super scary, as I haven't done them.

What you are talking about sounds really good on paper--hiking inn to inn. However, in reality, the topography of the situation doesn't necessarily match your desires.

For example, hiking Grindelwald to Wengen looks good on a map, but has problems. If you go up over the ridge via Mannlichen, you find yourself walking up, up, up, up most of the day, then at Mannlichen walking down a STEEP decline on switchbacks. Dangerous. If you walk via Kleine Scheidegg, the walk down to Wengen is a Long slog downhill that will begin to hurt your shins. If you decide to walk around the ridge via Zweilutschinen, you'll spend 99% of your time in the woods, then have a STEEP somewhat dangerous walk up to Wengen.

Now Murren down to Gimmelwald is totally safe, but only takes 20 minutes.

IF you do want to walk to a hut in a safer way, I'd suggest walking up to Lobhornhutte from Isenfluh. That's safe, tho tiring, and could take maybe 5 hours. It's best to have Tourist Info (in Lauterbrunnen) call the hut to say you're coming.

As for other hikes, click on my name and you'll see our dozen favorite hikes in the area, which have maps and pics. That way you'll actually SEE what you'll be in for. If you base yourself in Lauterbrunnen, and use transportation, you'll get the best views for your time.

Thank you for the input! We sort of suspected that it was more of a good on paper idea but we wanted some input from people who knew better.

We spent 6 days in Muerren last August. Some friends joined us there for a night as part of their inn-to-inn trek through the area on the Alpine Pass Route. They carried all their gear in backpacks, and their 18-month child as well. Here is their itinerary:

Arrived in Muerren by train and cablecar, one overnight. Then they hiked down past Gimmelwald toward Oberhornsee and spent two nights at the Berghotel Obersteinberg, with a day hike to the lake and back.

Then they returned to Muerren by cablecar from Stechelberg up to Gimmelwald, where we met them and brought them to our apartment in Muerren to spend the night.

Next day they hiked to Rotstockhütte. From there, over the Sefeinenfurka to Griesalp And another mountain inn (probably Golderli). Then over Hohturli and down to. Oeschinensee for a night at the Berghotel Oeschinensee.

We have stayed at this inn ourselves, on each visit to Switzerland.

The two passes between Muerren and Oeschinensee (Kandersteg) are high and steep, but only “treacherous” if there is snow, or in bad weather. Fortunately our friends got over the Hohturli and started down before the downpour started (this was an amazing storm that broke last summer’s heat wave, around the 7th or 8th of August. We were in Chamonix and impressed by the strength of the rain, and worried about our friends out there with their baby. But they are experienced mountaineers, and were not in any danger. They were able to find shelter in a farmhouse to wait it out before continuing down to the lake).

I have only hiked the part between Oeschinensee and Hohturli, and while it was steep and a bit slippery on the scree going downhill, it was OK with poles. I would not attempt that section without them.
