Direct flights connect daily Naples ‘Capodichino’ airport with several major European intercontinental hubs. Many low-cost companies also operate to/from Naples, particularly in the high season (April to October). Alternatively, you can fly to Rome ‘Leonardo da Vinci’ hub, and continue to Naples by train.
Trenitalia ‘EuroStar’ high-speed trains departing every hour link Naples and Rome central railway stations. The journey takes 70 min.
Public transportation in downtown Naples and the surrounding area is decent, and is expected to improve dramatically as soon as the several new subway lines under construction are completed (the time frame being uncertain mainly due to the delays caused by the continuous findings of archaeological sites during the excavation work). With one ticket (‘Unico’, € 1.20 fare) you can board all metro trains, public buses and tramways, and cable railways (funiculars) for a duration of 90 min from first boarding; this usually is more than enough to get to destination.
Taxis are reasonably priced. A flat fare (‘Tariffa pre-determinata’) can be requested to/from all hotels downtown and the airport, the central railway station and the main harbor.
The Department of Chemical Sciences of the ‘Federico II’ University, home to HTExplore, is in the neighborhood of Fuorigrotta, at the north-western reach of Naples. It can be reached in 15-20 min by taxi from the airport, and by bus (ANM lines R6, 180 and 615) from the railway station of Campi Flegrei. The latter is connected by a metro line (Linea 2) to Naples Central Railway Station (20 min trip).
