Downtown
Downtown caters to every taste, from the trendy Quartier Latin centered around rue Saint-Denis, to elegant rue Sherbrooke, where the Musée des Beaux-Arts de Montréal (1379-80 rue Sherbrooke ouest; +1 514 285 1600; fee) displays a world-class collection of historic and contemporary art. As if there weren't enough to see at street level, the Underground City offers some 18 miles of seamlessly linked pedestrian malls.

Vieux-Montréal
The narrow, cobbled streets and solid, centuries-old buildings of Vieux-Montréal, the once fortified old city, offer endless amusement. A lively nightspot, by day its galleries, boutiques, and historic sites entice. The colorful Vieux-Port harbors historic Chapelle Notre-Dame-de-Bon-Secours (400 rue St.-Paul est), where sailors prayed before setting to sea.

Maisonneuve
In the east-end area of Maisonneuve, visit Olympic Park (4141 av. Pierre-De Coubertin; +1 514 252 4141; fee to some sites), which includes the 1976 Olympic Stadium and boasts the world's tallest inclined tower. Nearby, the 185-acre Jardin botanique de Montréal (4101 rue Sherbrooke est; +1 514 872 1400; fee) contains about 30 outdoor gardens, notably the Chinese and Japanese, and the rose garden. The indoor Insectarium houses some 160,000 live and mounted insects.
