I had my eye on this route for a long time and planned it for my vacation. After 2 injuries this spring my fitness level wasn‘t the best but I decided to do the route anyway. (Backup plan was to stop in one of the villages)
I started quite early to avoid the heat and had the trails pretty much to myself for 3/4 of the time.
There haven’t been a lot of hikers, but quite some cyclists and motorcyclists at the pass roads I had to cross.
I can really recommend the tour, only downside is the ski infrastructure that pollutes the landscape at times. But the route has enough sections to make up for that.
