Hi Lauriesam, and welcome to MySwissAlps!
The places you mentioned are touristy indeed. Another factor counts as well though: the longer and more difficult a trail is, the less people you'll encounter. Graubünden is a good idea. Lots and lots of hiking trails there. I remember a hike in summer from Muottas Muragl via the Val Champagna down to Samedan. I think we only encountered one other couple at the end of the hike.
