Trail 507 B continues the path climbing from Vernazza: from San Bernardino it reaches the Cigoletta pass, at 607 metres on the Alta Via. It is 1.7 kilometres long and rated by the National Park for experienced hikers.
From San Bernardino you cross the forecourt of the sanctuary of Nostra Signora delle Grazie and enter the woods. You cross the road to Corniglia twice, then provincial road 51, and climb to Case Fornacchi, with a view down onto Guvano beach.
A dirt track leads on to the Cigoletta, where the path crosses the Alta Via delle Cinque Terre and continues, outside the Park, to Riccò del Golfo.
