Just before the town of Nasino, practically at the point where the road slopes steeper, in the "Mulino" area there is this beautiful arched bridge, in an excellent state of conservation... a good excuse to catch your breath before the climb!

“Montenero” is characterized by solar panels at the summit. A peak that is nothing special, but with a nice view.

Beautiful, almost shady little road inside a forest. The initial stretch from Caprauna is very steep (11-13%) and narrow. Once this section has passed, there are no longer any significant gradients and you ride in the shade of the forest, with wonderful views of the surrounding mountains.

Laura is the best cook I have met in Liguria! In addition to the excellent osteria, she runs the cozy bed & breakfast "I Tre Ladroni". When the restaurant is closed, she cooks an incredible menu for her house guests only. Here you will find a very hospitable and warmly managed accommodation. Reservation is mandatory. It is best to call Laura directly: +39 0182 77002
