“An exploration of the middle Valtellina valley.”— Franco Folini
- Don't forget to bring food and a light for the tunnels.
- This is absolutely not recommended in the winter. The second section is going to be blocked by snow. Every other season is great.
The most enjoyable part is the Decauville Arigna Vedello. It's an almost flat unpaved road closed to cars. The first section runs under the shades of old woods to end at Gaggio Reservoir. You'll need to follow the road that goes around the reservoir and then goes down to the connection to the second section. Ignore the signs telling you that the trail is closed, they are there just as a disclaimer by the electric company who owns the property (if something happens to you they don't want to be liable).
The second section of the Decauville Arigna Vedello is very wild and more exposed to the sun. It goes through a few very dark, but short, tunnels. You are going to need a light for the two longest tunnels. The experience of riding on the gravel in the dark is incredibly fun!
Once you reach the end of the Decauville Arigna Vedello (the place is called Vedello), I would recommend making an additional effort and go up to the ancient and beautiful village of Ambria as mapped. The village can be visited only by foot or by bike, the streets are too narrow for cars. From there, you can go back to the start by riding the Decauville Arigna Vedello in the opposite direction or following the paved road as shown..
