What time of year exactly Simon?
I ask as there is no way in hell i’d want to ride that area in June/July/August due to influx of tourists!
I was kind of one of them for my childhood as the family home was nearby.
Seriously though, I can highly recommend Eastern Switzerland (Davos, Lenzerheide, Arosa etc). Was there in 2011 and barely scratched the surface of the riding plus if you stay in rented accomadation in Davos and Arosa then lift tickets are free!!!
Heading back this September :-)
