To maximize your time in Naples, make use of public transportation like buses and trains to go from one site to another. Taxis are also available, but they can be expensive compared to buses and trains. Keep in mind that the traffic can be heavy, especially during peak hours. The best way to save money while traveling in Naples is to grab a day ticket for €3.50, which can be used for unlimited journeys.
If you have extra hours, consider adding a visit to the National Archaeological Museum. This museum offers the largest and most significant collection of Roman artifacts in the world, including Pompeian and Herculaneum art. On the other hand, if there are time constraints, you may consider skipping Napoli Sotterranea.
Naples International Airport (NAP) is the primary airport serving Naples. It is located about 4 miles northeast of the city center and provides international flights to several European countries. You can reach the city center by taking a taxi, airport bus, or Alibus, which operates every 20-30 minutes.
