The ascent to Passo Gavia from Ponte di Legno was made epic by the climbs of the Giro d'Italia.
The ascent seems calm and with rather wide road. This doesn't last long because after a few bends, the roadway becomes very narrow and the slope begins to be important.
Through a series of bends, you quickly gain altitude and prepare for the simple and very panoramic.
You then arrive at the tunnel, poorly lit but relatively short and straight, at the exit of which you have to face the last efforts on the last hairpin bends.
