Naples has 1.1 million people and 2,800 years of continuous history under Vesuvius. Catania was rebuilt twice from volcanic destruction and now makes the best arancini in Sicily.
Plan my Italy trip →Naples sits 12km from Vesuvius, which buried Pompeii in 79 AD and has erupted more than 50 times since. Catania was destroyed by Etna's lava in 1669 and then by an earthquake in 1693 that killed 16,000 people in the city alone, and was rebuilt in perfect baroque within 30 years using the volcano's own black stone. Both cities have a casual relationship with geological danger that outsiders find alarming and residents find simply factual. Both have extraordinary food cultures, chaotic street energy, and a complete disregard for being told what to do by anyone in Rome or the north. They are not interchangeable. But they rhyme.
They serve different functions in a southern Italy trip. Naples is the anchor of the Campania region — Pompeii, Herculaneum, the Amalfi Coast, and Capri all radiate from it. Catania is the base for eastern Sicily — Etna, Taormina, Syracuse, and the baroque towns of the southeast. Most people visit Naples as part of a Rome-Naples-Amalfi itinerary and Catania as the arrival point for a Sicily trip. Visiting both in the same journey is entirely possible but requires a flight or overnight ferry (Naples to Palermo, then travel east to Catania) — a serious commitment that makes for one of Italy's best long-form itineraries.
Naples was founded as Parthenope by Greek colonists around 800-700 BC and refounded as Neapolis (New City) around 470 BC. It grew into the largest city in the Roman Empire after Rome itself, and remained one of Europe's largest cities through the medieval period. The proximity to Vesuvius was not ignorance — Romans knew Vesuvius was a mountain of fire; they simply hadn't seen it erupt in living memory when Pompeii was buried in 79 AD. The eruption caught 20,000 people in a pyroclastic event so fast that many were killed mid-sentence, mid-meal, mid-argument. Naples survived. The Bourbon Kingdom of the Two Sicilies, with Naples as its capital, built the first railway in Italy in 1839 (Naples to Portici, running along the base of Vesuvius). The Neapolitan philosophical response to living next to a volcano has always been: have an excellent time now.
Catania's story is destruction and resurrection twice over. Etna's 1669 eruption sent lava flows directly through the western part of the city to the sea. Twenty-four years later, the 1693 earthquake that devastated the entire Val di Noto killed 16,000 in Catania and reduced the city to rubble. The response was extraordinary: within three decades, Catania was rebuilt entirely in Sicilian baroque, using Etna's own black basalt lava stone as the primary building material. The result is a city that looks genuinely unlike anywhere else in Italy — dark volcanic stone facades that glow orange in the evening sun, baroque palaces built from the remnants of what destroyed the previous city.
A genuinely unanswerable question because they come from completely different culinary traditions. Naples: pizza (the original, the standard by which all others are measured, full stop), fried food culture (cuoppo, pizza fritta, crocchè di patate, frittatine di pasta with béchamel inside), ragù Napoletano simmered for 8+ hours until the tomato and pork fat become indistinguishable, sfogliatella riccia for breakfast, babà al rum for dessert. Catania and eastern Sicily: arancini (the cone-shaped ones are Catanese — round ones are from Palermo — and the distinction matters locally), granita for breakfast with a brioche (ordering a granita al pistacchio or al gelso nero before 9am is completely normal), pasta alla Norma, swordfish 15 ways from the Catania fish market at La Pescheria (one of Europe's most dramatic food markets, operating since dawn), and cassata from a proper pasticceria. Both cities eat brilliantly and neither should be missed for food alone.
Naples is significantly more intense. It's seven times larger than Catania and carries the compressed energy of a city that has been continuously inhabited for nearly three millennia in a limited geography between the sea and the volcano. Catania is chaotic in the southern Italian way — traffic that ignores the logic of lane markings, double-parked scooters, fishmongers shouting at 5am in La Pescheria — but it operates at a smaller, more navigable scale. First-time visitors to southern Italy often find Catania a better entry point; Naples rewards return visits when you've calibrated your senses to Italian urban intensity.
Rome to Naples: Frecciarossa high-speed train from Roma Termini to Napoli Centrale (1h10, from €19 booked in advance, runs every 30-60 minutes). Rome to Catania: fly — Ryanair, Wizz Air, easyJet, and ITA all operate routes from Fiumicino or Ciampino to Catania Fontanarossa (CTA), 1h15 flight, from €25-50 booked weeks ahead. Flying is unambiguously better than the 7-hour train alternative. From Catania airport to the city center: Alibus (€4, 20 min to Piazza Stesicoro) or metro (Stazione Aeroporto on the FCE line, €1.10, 15 min to city center).
From Naples: Pompeii (35 min by Circumvesuviana train, €2.80), Herculaneum (20 min — better preserved, less crowded than Pompeii, completely absorbing), Capri (hydrofoil 45 min from Molo Beverello, ferry 1h20), the Amalfi Coast (seasonal ferry to Positano or Salerno train + coastal bus), Caserta Royal Palace (40 min by train — Versailles-scale baroque palace with fountains running 3km up the hillside, almost completely ignored by tourists). From Catania: Taormina cliff town (45 min by bus — Greek theatre with Etna as backdrop, one of the most beautiful theatre settings on Earth), Mount Etna cable car and 4WD crater tours (half-day, full day), Syracuse and Ortigia island (1h by train or bus — Archimedes's home city, Greek theatre still used for annual performances), Ragusa Ibla and the Val di Noto baroque towns (1.5h).
Catania is notably cheaper than Naples. A good hotel in Catania costs €60-80/night; a B&B or apartment €40-60/night. Naples B&Bs in the historic center run €70-100/night for something decent; the cheapest options cluster near Piazza Garibaldi (the main station area, perfectly safe, slightly rough around the edges). Restaurant meals in Catania: a proper sit-down seafood lunch with local wine runs €25-35/person. In Naples, Trattoria da Nennella lunch is €15/person; tourist-oriented restaurants near the main monuments charge €30-50. Street food in both cities is excellent and cheap: €3-5 for a substantial snack.
Both are hot. Naples in July-August averages 30-33°C with high humidity from the bay — the combination is taxing for extended sightseeing. The Camorra-run lido beaches (Posillipo, Marechiaro) and the ferries to Capri and Ischia provide escape. Catania in July-August reaches 35-38°C, with Etna's dark lava stone radiating heat — it's one of the hottest cities in Italy. The advantage: the beaches immediately east of Catania (Lido di Plaia, Aci Trezza with its black volcanic rocks) are genuinely beautiful and provide relief. Both cities become more local and less tourist-saturated in August — most tourists avoid peak heat, meaning restaurants and streets feel authentically Neapolitan and Catanese rather than tourist-service oriented. Come in September-October for the best weather compromise in both cities.
The Naples-Catania train is long (6-8 hours depending on service) and involves crossing to Sicily. The Intercity Notte service includes a car ferry crossing of the Strait of Messina — the train literally drives onto the ferry at Villa San Giovanni and drives off in Messina. This is an experience in itself and one that Italian children on school trips absolutely love, but it's not a practical fast-transport option. For most visitors, flying Naples-Catania (1h15, multiple carriers, from €25-50) is the sensible choice. Alternatively: Rome-Catania by air, or the 10-hour overnight ferry from Napoli to Palermo (then Palermo to Catania by train or car).
Visit Naples first on a southern Italy trip. Naples has international airports with direct connections from North America and most European cities, plus the excellent high-speed train connection from Rome. Use Naples as the base for Campania (Pompeii, Herculaneum, Amalfi Coast, Capri), then fly to Catania or Palermo to begin the Sicily section. This logic means your itinerary flows geographically without doubling back: Rome → Naples + Campania (4-5 days) → fly Sicily → Catania base for eastern Sicily (3-4 days) → fly home from Catania or Palermo. It's one of the best-structured southern Italy itineraries available.
Naples: cuoppo (paper cone of mixed fried items — pizza fritta, crocchè di patate/potato croquettes with mozzarella, frittatine di pasta/pasta fritters with béchamel), pizza a portafoglio (fold-it-like-a-wallet pizza, the street-eating format — get it from any friggitoria on Spaccanapoli or from Sorbillo's street counter), sfogliatella riccia for breakfast or anytime, and taralli (hard ring biscuits with lard, pepper, and almonds — the Neapolitan pretzel, not the Pugliese version). Catania: arancino con ragù or burro (the cone-shaped rice ball — order "con ragù" for meat sauce filling, "burro" for butter and mozzarella), granita al pistacchio di Bronte with a brioche from any bar before 9am, stigghiole (grilled intestines wrapped around green onions, sold from street carts near La Pescheria fish market — not for everyone but genuinely traditional), and panino con salsiccia e friarielli (sausage and broccoli rabe sandwich, echoing Naples but with a Sicilian sausage character).
Naples has one of the world's great museums in the Museo Archeologico Nazionale — the Farnese collection, Pompeii and Herculaneum frescoes and mosaics, and the Cabinet of Obscene Objects. The Certosa di San Martino (hilltop monastery turned museum above the Vomero neighborhood) has extraordinary Neapolitan Baroque and presepe (nativity scene) collections, plus panoramic views of the city and bay. Palazzo Reale on Piazza del Plebiscito is the Bourbon royal palace. Catania's museums are smaller but interesting: the Museo Civico in the Castello Ursino (13th-century volcanic stone castle) covers Sicilian history; the Museo Diocesano holds cathedral treasures including works rescued from the 1693 earthquake; and the contemporary art space at the Ex-Monastero dei Benedettini (now part of the university) is architecturally stunning — a baroque monastery rebuilt after 1693 at extraordinary scale.
Naples: October and March are the sweet spots — mild temperatures (15-20°C), reduced summer crowds, lower hotel prices, cultural programs fully operational. May and June are also excellent (warm, before the peak season). July-August is hot and humid; the city empties of locals somewhat as Neapolitans escape to the coast. Catania: April-June and September-October, for similar reasons — 20-26°C, manageable crowds, lower prices. April on Etna's slopes is particularly beautiful as vegetation returns after winter. The Catania Sant'Agata festival (February 3-5) is one of Sicily's most extraordinary religious celebrations — hundreds of thousands of participants following the relic procession through the city streets in white tunics — worth planning a February visit around if you're interested in Catholic popular culture at its most visceral.
