Fantastically scenic route with too many bends to count and views of Mont Blanc. The surface on the Italian side is not good, but at least there are Armco barriers, which disappear on the French side. The Italian bends are very tight, alot of hairpins, but the French ones are more open. There was some snow around near the top even in June.
Mostly medium/high speed flowing bends and some good straights. Midway Cafe (just south of Whitchurch) is a nice place to stop on this route.
