Consider walking the path of the Gods to or from Praiano. You can pick this up from Nocelle or Montepertuso. It's altitude is about 500m and you should allow three hours to get to Praiano. If coming the other way and are looking for an inexpensive restaurant eat at Nocelle, the ones in Montepertuso are posh and charge Positano prices. From Praiano you start out by following the path to the convent of St Dominic. The path clings to the mountainside in the same way as the road does lower down so it is not suitable for people with vertigo and it is rough in places. You can pick up a map with all the local hiking trails from the tourist office for one euro. There is a local bus that runs between Praiano and Positano and also between Positano and Nocelle.
