This happened purely by accident, but turned out awesomely:
On our visit to Sorrento in early March, one rainy day for something to do we took the SITA bus to Positano, about a 45 minute ride across the peninsula. We were told to disembark at the second Positano bus stop, Sponda. But we had never been there before, and people kept ringing the bell to get off, so long story short we got off the bus two stops early, on the middle of a cliff road in the middle of nowheresville. What do we do now?!
So we started walking. Fortunately, the rain had stopped, the sun had peeked out and we were on a slight downhill grade on the narrow road towards Sponda. It was a little more than a mile, but I have to say it was one of the more pleasant & spectacular walks of our lives, around curves and bends and different wonderful vistas with each turn. Maybe the highlight of our trip.
Point being had we been on the bus, no way would we have experienced this scenery in the manner we did. If you're outside walking on the coast anywhere from Positano to Cetara, you're going to see some magnificent stuff, I guarantee it.
