Beautiful place and beautiful river, with water, as it was flowing today.

A beautiful stone bridge. The climb afterward is quite rocky, and you'll have to walk for a bit.

Although you go up by road, it is a very nice climb with relatively little traffic, other than the motorcycles that are going to enjoy the curves. We, on the other hand, will twist with each curve in which the slope increases. Harder than the numbers say
