West to east, not the smoothest way, while it will be a fantastic hike, the whole stunning panorama always lays behind you. The path goes up and down from ~430 mamsl (metres above mean sea level) of Nocelle, in Positano (SA), to ~630 mamsl of Bomerano, in Agerola (NA). You’ll have the sun in front of you in the morning. In the afternoon the sun will warm, and during summertime will burn, you until the sunset behind Capri island.
Walking the path in this direction (from Nocelle to Agerola or Praiano) tends to be slightly more uphill then walking in the other direction.
A really good map, made by Giovanni Visetti, is available here.
A Google maps overview is just below, take it is a merely overview of the paths.
