Bossico Colombina
Departure from Bossico. I recommend stopping at the parking lot of the sports field. Ascent following in the first section the Nero MTB route signs, part asphalt and part on well-maintained mule tracks with fun ups and downs. Near Colombina you take the climb to the summit from the north side, easier although you will need to push or shoulder a little. Don't worry the difficult section is not very long. At the summit you forget everything. The panorama overlooking Lake Iseo is spectacular.
The descent I did from the south side of Colombina and I won't hide the fact that at times I walked down because of the steep slopes and the bumpy bottom. Even here the hard section (at least for me) is short. We then continue following the Nero MTB route in Bossico returning by Ceratello and the beautiful new scenic road that is always very scenic.
The ride ends back in Bossico at the parking lot.
