I took it from Italy to Swiss, while I was sleeping in Campodolcino. It´s really nice, but surface is not the best.
We rode from Swiss side into Italy in June 2012. The ride up to the summit was scenic with plenty of enjoyable sweeping bends. Dropping down into Italy was \"challenging\" but still enjoyable. Take care when exiting some of the unlit tunnels, often wet and straight onto tight hairpins. Brilliant scenery.
Splugen pass is open with just a few cows for company on the north side.
A pleasant ride around Montespluga lake then after Pianazzo enter the challenging drop into Italy with hairpins in narrow tunnels and spectacular runs down into the valley below to Chiavenna
Did this in July 2009, amazing bit of tarmac, when going the route suggested above look out for impatiant Italians in batered Fiat Puntos making progress as they take no prisoners. On the Italian side the road can go quickly from bright sunshine into pitch black wet tunnels.
Not a very well-known pass but its a beauty. Great tarmac and good visibilty make this pass to one where you can really open the trottle if you get the chance. In the beginning it is pretty straight forward but pretty fast after the Italian border the sharp turns and switchbacks build up rapidly. When descending into Italy, you will arrive at a T-junction. If you want to be thrilled beyond believe go left (i.e. the direction which is forbidden for trucks and campers). You will find a steep descend into various blind corners in and out of tunnels on a narrow road. Not for the faint-hearted or mountain-newbies, but a challenge for the advanced riders.
When arriving in Chiavenna, follow the SS37 back into Switzerland to the Maloja-pass and Julier-pass: both open and insanely fast.
