There are two spots from which to admire the water falling from the rocks, the larger one is the Canepa waterfall, and not far away there is a smaller spot, still on path 2.

This second part - for those descending from Monte Scudo - is equally interesting in particular because two refuges from the Second World War are clearly visible. Attention ⚠️ the first part of the path is covered by vegetation (at least during the summer when I walked it). There are so many joints that it's really hard to see where you're going. Follow the trail. The second part of the path after the caves is much cleaner probably because it is traveled from below from where there are signs for the provincial sp41 after Trarivi (near the church of Peace)

Interesting to see, it's not clear to me if they were military posts or for civilians. In shelter 2 there is stagnant water

Beautiful hidden path in the Canepa forest (San Marino). You reach the old mills. The descent in some sections is impossible ... some sections you have to abseil with a rope, in others you have to pull yourself up with a rope ... To try for those who love adventure and a type of MTB out of the conventional.
