The Amalfi Coast is packed from Easter until late September, so if you are looking for solitude, visit in the spring and fall. Note that many hotels and restaurants close for the winter season. Visas are not required for leisure visits of up to 90 days in the overall Schengen area. The nearest airport is Capodichino in Naples, but Rome's Aeroporto di Fiumicino handles intercontinental flights. From Naples you can arrange a private transfer or take the train and bus to the coast. The area is well served by the SITA bus company and there are plenty of taxis. In high summer, there is also a boat service between the main coastal towns. The currency is the euro and electricity is 220 volts.
