An interesting variant that makes it possible to avoid a good part of the busiest kilometres of the SS27; until the reunion with the state road, the route runs on roads with little or no traffic that pass through pleasant villages in a very pleasant environment. After the reunion with the SS27, the route is the same as the classic side. A nice alternative for those who wish to enjoy the mountains in greater tranquillity than they would following the normal route.... read more

Positively surprised. The traffic is really bad but up to the entry to the tunnel there is often a very generous shoulder (easily 1 car width) you can ride onto. The last part is a gem: much prettier than the Swiss side, with wide meadows instead of steep valleys, and there are a few nice places to stop for a quick coffee or to get some water. The tunnels are much shorter. You can almost see the end from 7 kilometers before (the Swiss side is hidden until the last 300 meters).
Overall it's also much easier, I've never seen anything above 10％, and the slope itself is more regular. Still a very long climb, be prepared.

Variante interessante che permette di evitare buona parte dei Km più trafficati della SS27; fino al ricongiungimento con la Statale il percorso si snoda su strade con traffico ridotto se non nullo che attraversano piacevoli paesini in un ambiente molto gradevole. Dopo il ricongiungimento con la SS27 il percorso è lo stesso del versante classico.
Una bella alternativa per chi desidera godersi la montagna in maggiore tranquillità rispetto a quanto farebbe seguendo il percorso normale
