Just recently had a pretty nice 4-day-trip through the Alps :-)
From Stuttgart, Germany to Switzerland via Klausenpass, up to the Sustenpass, Wassen, to the wonderful Grimselpass & Furkapass, Passo San Gottardo, Lago Maggiore (ITA), Valle Versazca (CH), Lago di Como (ITA), Passo San Marco, Passo di Zambla, Passo Gavia, Passo dello Stelvio, Ofenpass and soooo many other nice roads back to Stuttgart :-)
All in all about 1743kms.

This here (Passo Stelvio, ITA) is just one of a lot of nice videos ;-)
