There is an area, West of Sondrio, where you can't do without noticing the sunlit terraced vineyards where the Valtellina Superiore Sassella DOCG is produced. 

The first part of the tour crosses the typical terraced vineyards of the Rhaetic Alps, offering wonderful sights of the river Adda and the valley floor. In the second part of the tour, connecting Castione Andevenno to Sondrio, the route is almost entirely flat and crosses Parco Bartesaghi, that is Sondrio's most important green area. 

Two places touched by the route are definitely worth a visit:

• SANTUARIO DELLA MADONNA DEL SASSELLA 
  The Sanctuary was built Nestled on a rocky spur in the Fifteenth century and has become one of the symbols of this area, as it can easily be seen from the state road.  
   
• ROCK ENGRAVINGS LA GANDA, CASTIONE
  A recent discovery shed light on La Ganda (Castione Andevenno): a rock engraved about 3,000 years ago. There are a great number of engravings and most of them have antropomorphic features.
