SoggiornaTrail 528C, the Via der Predao, is a short connector between the 528 and the 528V above Persico beach, below Campiglia: under 400 metres and about twenty minutes according to the National Park.
It crosses the abandoned sandstone quarries and runs along a slope made of the waste from stone working. The story goes that the blocks were slid down into the sea, loaded onto barges and delivered to the shipyards of Genoa and even to Argentina.
Services are in Campiglia; there is a water point at Persico beach.
