Starting Point of the Hike is Vernazza
The first part from Vernazza to Muro can be taken by minibus. Muro is a residential area above Vernazza. There are a few vacation rentals with nice views, but no bar or supply point. Then you climb from Muro on the narrow path that runs between the vineyards to San Bernardino. Alternatively, you can take the bus up to San Bernardino and start the hike there.
