About Genoa

The Porto Antico holds the aquarium and the Renzo Piano-designed waterfront, while the narrow caruggi behind it lead to San Lorenzo's striped cathedral and the Rolli palaces of the old aristocracy. Focaccia, pesto, and farinata come from the city's own kitchen, and funiculars and public lifts save the steepest climbs. Mild sea air in April through July comes before the summer humidity peaks.

Travel Tips

01Portico Shade Midday
Use covered streets (carruggi) to escape midday sun. Palazzo Rolli interiors are cooler morning visits before cruise passengers fill Via Garibaldi.
02Metro Elevators & Elevators
Public elevators and the metro help with Genoa’s vertical geography. The aquarium and Porto Antico are flat; old-town climbs reward sturdy shoes.
03Aquarium Timed Entry
Acquario di Genova sells timed tickets that vanish on rainy weekends. Rolli palaces often share combined tickets during Genoa events.
04Pesto & Port Safety
Trattorias inland from the front often serve better focaccia and pesto than the first tourist row. Watch belongings in crowded ferry queues.
