A staple loop that's rideable all year. Join this route from absolutely any village and add in extra climbs if you're feeling fresh. Up and down, fast and furious. Cuteness overload with some of the villages.
Year-round but watch out for the shady descent into Val Masino as it can be treacherous in the depths of winter. Your alternative is to descend to Morbegno from Dazio on a beautiful, newly tarmacked fast road.
