Naples Travel Guide: Pompeii and Vesuvius, Patron Saint Festivals, Procida Hydrofoils and Weather by Month

Naples is the base for Pompeii, Herculaneum and the Vesuvius crater trail, with the Pompeii park spreading out to Boscoreale, Oplontis and Stabia. It suits travelers who like their days split between ruins, museums and a boat ride, and SNAV hydrofoils leave the port for Procida every day of the year.

Cars are the catch. Naples runs limited traffic zones that close some streets to vehicles, including via Ferdinando Russo and via Marechiaro in summer, and the city says its tourism keeps growing. Go by foot, ferry and shuttle where you can, and read the driving rules at the end before you rent anything.

Where is Naples and what is it like?

Naples is a port city. Mount Vesuvius sits behind the city, and the trail to the crater starts in Ercolano.

The center is a dense line of palaces, castles and chapels. The Palazzo Reale stands at the southern edge of the ancient city, its façade facing west toward the Largo di Palazzo. Castel Nuovo has a trapezoidal plan with a tuff curtain wall and five cylindrical towers. The National Archaeological Museum is at Piazza Museo 18/19 and the Sansevero Chapel is at Via Francesco De Sanctis 19/21. Gallerie d’Italia is on Via Toledo at number 177. Farther out, Secondigliano has its own walking itineraries.

The Palazzo Reale was founded in 1600 as the palace of King Philip III of Spain, and Naples became the capital of an autonomous kingdom under Charles III of Bourbon in 1734, when the palace was enlarged. Castel Nuovo was a cultural center under Robert of Anjou, with Giotto, Petrarca and Boccaccio staying there.

What is there to do in Naples?

Pompeii, Herculaneum and the Great Pompeii sites

The standard Pompeii ticket covers the ancient city and its suburban villas, the Villa of the Mysteries and the Villa of Diomedes. It also includes Villa Regina in Boscoreale, with its Antiquarium, and the shuttle bus.

A second ticket, Pompeii Plus, covers Oplontis, Villa Arianna, Villa San Marco, the Archaeological Museum of Stabiae, Boscoreale and the shuttle. The Great Pompeii is a widespread park made of Pompeii, Boscoreale, Oplontis and Stabia, and a shuttle service called Pompeii Artebus connects all the sites. Choose the ticket by the sites you want to see.

Herculaneum Park has its own list: the Archaeological Area, the Theater, the Villa of the Papyri, the Antiquarium and the Boat Pavilion. Two thematic itineraries at Pompeii, Civic Pompeii and Daily Pompeii, last about 1.5 hours and cost €8 on top of the entrance ticket. They suit anyone who wants a guided thread through the site.

Vesuvius and the Great Cono trail

The Great Cono is nature trail no. 5. It starts at the square at 3,281 feet (1,000 meters) above sea level in Ercolano. From the square you can see the northern slope of Mount Somma, with Punta Nasone, the peak of the ancient volcano, at 3,714 feet (1,132 meters).

The hike takes up to 2 hours on the shortest route and up to 3 hours on the longest. The park caps the Great Cono at 360 hikers per hour, so an early start makes sense on busy days. The high route on the crater summit is closed to visitors for safety and environmental protection.

Access to the crater is through the automatic gate at the Piazzale di Quota 1000 in Ercolano, or the gate at the Piazzale di Quota 1050 in Ottaviano.

Museums, palaces and the Sansevero Chapel

The National Archaeological Museum of Naples is at Piazza Museo 18/19. The Sansevero Chapel, also known as S. Maria della Pietà, was founded in 1590. From 1749 Raimondo de Sangro devised its decorative program himself, and Giuseppe Sammartino made the Veiled Christ at the center of the chapel.

Castel Nuovo houses the Museo Civico. The route takes in the Sala dell’Armeria, the Cappella Palatina (also called di Santa Barbara) and the first and second floors of the southern curtain. The courtyard has a low-arched portico and an external piperno staircase by Guglielmo Sagrera.

The Palazzo Reale is a museum and gallery, ceded to the State by Vittorio Emanuele III of Savoy in 1919. Gallerie d’Italia offers a physical or virtual audio guide through its app, or a guided visit with a cultural mediator.

Procida and the islands by hydrofoil

SNAV hydrofoils connect Naples to Procida with daily departures all year round. Procida is the smallest island of the Campania archipelago, with views among beaches, bays and inlets. Boats also link Procida to Ischia, arriving at the Casamicciola port.

SNAV also sells a Capri Experience boat excursion with a stop at the Blue Grotto.

Archaeology fans should give the most days to Pompeii, Herculaneum and the museums. Hikers should keep a morning free for the Great Cono. Anyone who wants water and slow views will like Procida, and the free guided walks in Secondigliano, from September 21 to November 23, suit people who want a side of the city beyond the center.

When should you go to Naples?

May and June are the easiest months for walking. May brings highs of 75°F (24°C) and about six rainy days. June is warmer at 82°F (28°C), with only about three rainy days and a sea at 73°F. September keeps the water warm at 76°F, with highs of 80°F (27°C), though rain returns at about six days in the month.

July and August are the hottest, with highs of 87°F (30°C) and 88°F (31°C). They are also the months for the sea, which reaches 79°F in August. Heat matters most for the Pompeii ruins and the Vesuvius trail, so start early in those months.

Festivals run through the warm months. The 2026 patron saint calendar opened on June 1 at 9 p.m. with the Festa di Sant’Erasmo and closed on October 17 with the Festa di San Gaetano Errico. In between came the Festa del Carmine on July 15, the Solemn Mass for San Gennaro on September 19 at the Duomo, and the Festa dei Gigli di Barra from August 31 to September 28. Estate a Napoli ran from July 2 to October 8. Patron saint events include solemn masses, processions, concerts and shows, and they are free.
