The train stations on the Circumvesuviana line serving the Sorrentine Peninsula are Meta, Piano di Sorrento, Sant'Agnello, and Sorrento, in order of increasing distance from Naples. The main transport hub for cheap, efficient bus services radiating to destinations along the coast and inland is the Circumvesuviana station in Sorrento.
If heading to Sorrento from Naples, use the Stazione Centrale (Piazza Garibaldi), which is the second stop on the Circumvesuviana line as it departs from Naples. Follow the "Circumvesuviana" signs, which will take you through the ticket barriers down into the train stations.
