By Plane
The nearest International Airport is Capodichino (code NAP). Once you have arrived, you'll have to take one of the methods listed below to cover the final leg of the journey.
From the airport you can take a bus for €3 (called Alibus) to Stazione Centrale in Naples (get off here for connections to Salerno via train). It also stops on Piazza Municipio near the ferry port, from which you can take a 5-minute walk to catch the Bus (SITA). The route is not obvious, so see the section below.
You can buy your ticket on the Alibus, and you can get to it by walking right out of the airport terminal to the bus stop which is less than 20 metres from the airport terminal exit.
From Naples Airport there is a SITA bus running directly to Salerno (Euros 7). This bus runs only 4 times a day, and not on Sunday. You have to walk some 300 meters to reach the bus-
By train
From Napoli Central or Piazza Garibalidi you can easily reach Salerno by train. The regional trains ticket to Salerno costs around €3-€4 and it's called U-5 Unico Campania. Other trains are more expensive and cost around 7-10 euros.
BY RENTAL CAR
Theoretically, you can rent a car to cover the last stretch of the journey, but in all honesty it's probably better to reserve this option for second (or third) visits to the area if you are used to driving in Northern Europe or the US. The reason for this is that driving habits in this area of Italy have developed in a sort of local micro climate - most cars drift around on the motorway hovering between two or three lanes, most drivers talk and gesticulate instead of driving, and if you don't keep up with the traffic flow, you are likely to find someone tailgating you within 30 seconds or so.
If you need any more convincing, take a look at the cars when you arrive in the area. There is a prize if you can spot one without dents. Dents and rental cars don't mix well
