About Portofino

Portofino is a tiny terraced village wrapped around a horseshoe harbor—yachts, aperitivo bars, and the Castello Brown lookout above the Gulf of Tigullio. April to June and September deliver the best compromise: sea warm enough for swimming at Paraggi, hiking the Sentiero to San Fruttuoso, and terrace lunches without the August parking nightmare. July weekends fill with day-trippers from Genoa; arrive by ferry from Camogli when possible. Winter is quiet and moody, perfect for photography, though many boutiques close until Easter.
