Regions to know
To frame your trip by what you have time for and what you're after.
Lazio (Rome)
Rome, Tivoli, Ostia Antica, Castelli Romani
The eternal city plus easy day trips: Tivoli for the villas, Ostia Antica for Pompeii's underrated cousin. Most international flights land at Fiumicino. Three days minimum just for Rome itself.
Tuscany
Florence, Siena, San Gimignano, Chianti, Pisa, Lucca
Florence as base, then hill towns and Chianti wineries by car. Lucca's intact Renaissance walls, Pisa's tower (90 seconds and you're done — don't sleep there). The most photographed countryside in Europe.
Veneto (Venice)
Venice, Verona, Padua, Vicenza, Dolomites nearby
Venice itself plus day trips: Verona (Romeo & Juliet, summer opera), Padua (the Scrovegni Chapel — Giotto's frescoes), Vicenza (Palladian villas). The Dolomites are two hours north by train.
Liguria & Lombardy
Cinque Terre, Portofino, Genoa, Milan, Lake Como, Bergamo
Italy's wealthier, faster half. Cinque Terre and Portofino for the coast, Genoa for the underrated old port. Milan for fashion + food + Brera, Lake Como and Bergamo for the calmer alternative.
Campania (Naples)
Naples, Amalfi Coast, Capri, Pompeii, Paestum
Pizza birthplace, ancient Rome (Pompeii, Herculaneum), the Amalfi Coast, Capri's grottoes, the Greek temples of Paestum. Loud, intense, magnificent — and Italy's most affordable south.
Sicily
Palermo, Catania, Mt Etna, Taormina, Agrigento, Noto
An entire-trip-on-its-own region. Palermo and Catania for street food, Etna for the volcano, Taormina for the Greek theatre, Agrigento for the temples, Noto and Ragusa for Baroque hill towns. Feels closer to North Africa than Milan.
