There is a stretch of approx. 5km suitable only for mountain bikes and only for experts. With a trekking bike you have to push.

We did the tour in reverse order and left at Porto Ercole. Very nice because then you quickly have the unpaved part and all the climbs, and lunch in Porto Stefano is perfect😄

Only possible with an eBike. Some parts of the road in the mountains are very rocky and steep. Overall one of the most beautiful tours I've ever done. The views are sensational.
