Swiss Areas?

Hey,

Looking to solo travel to Switzerland, mainly for scenery/hikes, my second option was Norway. However, I always hear people say that Interlaken isnt the best spot to go to, as its over touristy etc, as well as Grindelwald. Is there any other regions apart from the Bernese Oberland that has great scenery and is perhaps underrated, whilst having good transport to hotspots like cities etc. I have heard Thun mentioned for the Oberland area too, but need more thoughts.
