During the sixth leg into Naples, Seamus Elliot (Helyett-Pontin) attacked from the leading breakaway as the stage came to a close, primarily because of sprinter Miguel Poblet's (Ignis) presence in the breakaway. He went under one kilometer left before he cramped with remaining and was overtaken. Poblet won the stage, while Elliot held on to get 10th place. The next day's stage was a climbing individual time trial along a road on Mount Vesuvius, which ended at the observatory on the volcano. As the riders began the time trial in reverse of the standings for the general classification, contenders Anquetil and Gaul were the final two to get on the course. Anquetil again chose a larger gear (45 x 20), while Gaul chose a smaller gear (45 x 23). Anquetil was faster over the initial stretch of the race which covered the cobblestones, but after that stretch, Gaul closed the gap. Gaul finished eight seconds after Anquetil did, winning the stage by 37 seconds over Guido Boni (Tricofilina). A time trial followed the next day, but this time it was around the island of Ischia. The course was rather hilly and was won by Antonino Catalano (Bianchi), while with respect to the general classification, Anquetil managed to gain 22 seconds on Gaul.
