Île Sainte-Marguerite, 06400 Cannes, France
From the Vieux Port it's a 15-minute, €13.50 round-trip to Île Ste-Marguerite. Its Fort Royal, built by Richelieu and improved by Vauban, offers views over the ramparts to the rocky island coast and the open sea. There are two restaurants—L'Escale and La Guérite (both closed from mid-October to spring)—on the island, but they're rather pricey—you are paying for food with a view.
