The rhythmic road to the Sufner lake is followed by gravel to probably Switzerland's most beautiful pass. It gets steep after Splügen, although without any really nasty inclines. You're rewarded at Lai da Vons with wide views, including to the Rheinwaldhorn. The descent to Andeer? Long, rapid and very bumpy.
