Naples Travel Guide: Days, Transport, Timing, Safety, and Budget

Plan two to three days in Naples, walk the compact old center on foot, use the Line 1 metro and Alibus for the longer hops, aim for late April to early June or September, and treat the city with ordinary big-city caution rather than fear. Naples rewards travelers who slow down and move at their own pace, and its historic core is small enough that the best way to see it is on your own two feet with something in your ears telling you what you are looking at.

Here is the practical planning, verified against current sources, followed by how to route your walking days through the city's three self-guided Naples walking tours.

How many days do you need in Naples?

Two full days covers the historic center comfortably. Three days lets you add the layers most visitors skip.

The old town, the part laid out on the ancient Greek grid, is genuinely small. You can cross it end to end in under half an hour on foot, which is why walking beats every other mode inside the center. On a first day you can trace the long straight street the locals call Spaccanapoli and see the major churches along it. A second day takes you below ground into the aqueducts and excavations, and up into the Sanità quarter to the north. If you are also planning a day trip to Pompeii, Herculaneum, or the coast, add that as a separate day rather than squeezing it in, because the Circumvesuviana regional train eats several hours round trip.

If you only have one day, spend it walking the straight cut through the old center. It gives you the churches, the workshops, and the street life in a single continuous line.

How do you get around Naples?

Walk the historic center, and use the metro plus the airport bus for the longer distances. The center is dense and largely flat along its main axis, so on foot you lose nothing to traffic and gain the small discoveries that make the city.

For distances beyond walking range, Naples has a metro, buses, and three funiculars. Metro Line 1 is the one to know: it doubles as an underground art gallery, with stations like Toledo, Università, and Museo designed as installations. A single ANM ticket costs about €1.50 and a 24-hour ticket covering metro, bus, and funicular runs about €4.50, so if you plan more than two rides in a day the day ticket pays for itself. Validate paper tickets when you board.

From the airport, the Alibus shuttle connects Capodichino to Napoli Centrale station and the port for about €5 one way, running roughly every fifteen to thirty minutes from early morning until around midnight. It takes about fifteen minutes to the central station. A taxi to the center runs on fixed airport tariffs, so agree the fare before you set off.

One honest note on the streets themselves: Naples pavements are old, uneven, and often crowded with scooters. Wear real shoes, not sandals, and keep half an eye on the ground.

When is the best time to visit Naples?

Late April through early June and the first half of September are the two windows worth aiming for. Both give you temperatures in the low twenties Celsius, walkable streets, and sites you can enter without long queues.

Summer, from late June through August, is hot and busy. Midday heat in the narrow, sun-trapped streets of the old center is real, and if you visit then, walk early in the morning or after four in the afternoon and keep water on you. Winter is quiet and cheap, with mild days and occasional rain, and it is the cheapest time for accommodation apart from Christmas week. Spring and autumn sit in between on both crowds and price. September is often singled out as one of the best months for most travelers: warm, less crowded than high summer, and with the local rhythm returning as residents come back from holiday.

Is Naples safe?

Yes, with ordinary big-city awareness. The realistic concern is petty theft, mostly pickpocketing and bag snatching in crowded spots, not violence against visitors, which is rare.

Naples carries a rougher reputation than the daytime reality of its tourist areas supports. Reported crime figures place it below several other major Italian cities, including Rome, Milan, and Florence. The sensible precautions are the same ones you would take in any large European city: carry a cross-body bag and keep it in front of you in crowds, do not put your wallet or phone in a back pocket, and be alert to distraction tactics, where one person engages you while another works your bag. Busy markets, packed metro cars, and the areas around major sights are where hands go to work. Stick to well-lit, populated streets after dark. The historic center is fine for daytime walking, which is exactly when you will be doing these tours.

What does a trip to Naples cost?

Naples is one of the cheaper major Italian cities, especially for food. A classic Neapolitan pizza in a working pizzeria costs a few euros. Coffee at the counter is under two euros. Public transport is inexpensive, as noted above.

Sites vary. Many of the churches on the walking routes are free to enter, including the main cathedral. Ticketed sites are modest: the cloister at Santa Chiara, the guided descent at Napoli Sotterranea, the Bourbon Tunnel, the San Gennaro catacombs, and Cappella Sansevero each charge a small entry fee, generally in the range of six to fifteen euros. Cappella Sansevero uses timed entry and sells out, so book it ahead. Budget travelers can see a great deal of Naples on foot for very little, since the streets and squares themselves are the main attraction.

Your three walking days, routed

Naples splits cleanly into three self-guided audio walks, each with a different way of reading the city. All three are on the /italy/naples city page and play GPS-triggered narration as you walk, so you set the pace and stop whenever you like.

Start with The Straight Cut, the Spaccanapoli walk. It follows the dead-straight street that splits the old city in half, a line first surveyed by the Greeks, past Gesù Nuovo, Santa Chiara, Cappella Sansevero, the Christmas-crib workshops of Via San Gregorio Armeno, and the cathedral. It is about ninety minutes of walking over roughly two and a half kilometers, moderate underfoot. This is the one to do first because it gives you the geography of the whole center.

On your second day, go under and around. The City Below reads Naples as a hollow city, following the void carved into the soft tuff stone beneath the streets, from Napoli Sotterranea and the San Lorenzo excavations down toward the sea and Castel Nuovo. Then The Quarter They Feared climbs north into the Rione Sanità, the neighborhood the city once wrote off and which has rewritten itself from below, taking in the San Gennaro catacombs, the double-helix baroque staircases of Palazzo dello Spagnolo and Palazzo Sanfelice, and the bone-lined Fontanelle cemetery. The Sanità walk is the longest and hilliest of the three, so save it for when your legs are warmed up and start it in the cooler morning hours.

Book the timed-entry sites (Cappella Sansevero, the underground descents, the catacombs) before you set out, and let the walks carry you between them at whatever pace suits the day.
