Museum of the Sea

Lonely Planet review

As you get off the boat at Île Ste-Marguerite, a map indicates a handful of rustic restaurants, trails and paths through the cool eucalyptus and pine forest. It also directs you to the 17th-century Fort Royal, which now harbours the 'Musée de la Mer'. Make sure you explore the old state prisons, built under Louis XIV, and see exhibits of the fort's history.
