>>1890476Close but no cigar, there's a succession of five cable transports between Arosa and Lenzerheide, but three are chairlifts. If they allow pedestrians on them you could do it, which I doubt at least in winter with all the skiers and snowboarders.
Honestly, this seems like an instance where it would actually make a lot of sense, since it would offer a much more convenient connection than any conventional route.
