Fodor's Expert Review Île Ste-Marguerite

From the drop-off point on Île Ste-Marguerite, walk left for 10 minutes to see the Fort Royal. Built by Richelieu and improved by Vauban, the fort offers views over the ramparts to the rocky island coast and the open sea. On the southern side of the island, you'll have to get wet to see the underwater eco-museum: its six statues are submerged 92 to 144 yards from the shore at a depth of 10 to 16 feet. The island's two restaurants—L'Escale and La Guérite—are both closed from mid-October to spring. They're also rather pricey, and the service is not as good as the fish; you are paying for food with a view. Public toilets are accessible.
