If you are traveling by train (tel. 892021 in Italy; www.trenitalia.it), the closest station is Vietri sul Mare, on the local line between Naples (where you'll change trains if you are coming from the north) and Salerno (if you are coming from the south).
By car, take autostrada A3 toward NAPOLI-SALERNO to the exit for VIETRI SUL MARE. Follow the signs for VIETRI, MAIORI, AMALFI, and POSITANO; they will lead you to the famed SS 163, the coastal road that meanders from Salerno to Positano and a bit beyond. You can also reach SS 163 from Castellammare di Stabia, Piano di Sorrento, Vico Equense, and Sorrento heading east and following signs for POSITANO and AMALFI. Note: Because of the solid traffic here in summer, local authorities have occasionally limited car access to SS 163; check with the tourist office and your hotel before making your plans.
