In 2012, four of us aged between 59 and 68 in average physical shape hiked the high trail from Volastra to Corniglia and did not find it difficult. We took a bus from Manarola to Volastra which saved a lot of uphill hiking. We then walked the black trail in the picture to the orange trail into Corniglia. We had a drink in the main part of the town to celebrate us grandparents doing this hike then took a bus down to the train station. The scenery was incredible and we highly recommend doing it.
