Basilique Notre-Dame de Montreal: The ornate Basilique Notre-Dame de Montreal, an early 19th-century cathedral, boasts 228-foot twin towers and one of North America's biggest bells. Inside are intricate wood carvings, a magnificent organ with more than 7,000 pipes and a brilliant blue ceiling strewn with gold stars. (116 rue Notre-Dame Ouest; 866-842-2925)

Vieux-Montreal: Also known as Old Montreal, this area was home to the city's first European settlers, who arrived in the mid-17th century. Many of the homes and buildings have been restored, and the old city has wonderful boutiques, sidewalk cafes and street performers. The center of the action is Place Jacques-Cartier, a pedestrian mall. Nearby, Vieux Port is one of Montreal's best-loved recreation spots; this waterfront park is a terrific place to take a stroll or sign up for speedboat rides and sunset harbor cruises. You can even rent paddleboats and join a Segway tour.

Parc du Mont-Royal: Bike, walk or even take a horse-drawn carriage ride through Parc du Mont-Royal. Designed by Frederick Law Olmsted (designer of New York's Central Park), it's composed of nearly 500 acres of forest and winding paths and lies atop the mountain in the heart of Montreal. On the way down from the mountain, stop by St. Joseph's Oratory (3800 chemin Queen Mary), a massive domed shrine to Canada's patron saint.

Montreal Museum of Fine Arts: This is the city's premier repository of art representing numerous eras and styles, from 19th-century European masterpieces to Native American and Inuit artifacts. (1380 rue Sherbrooke Ouest; 514-285-2000)

Shopping: Montreal is a shopper's delight. Three major areas include rue Sherbrooke, which is known for its fashionable designer boutiques and gourmet restaurants; rue Ste.-Catherine, located in the downtown area, where you'll find major malls like the Eaton Center; and boulevard St.-Laurent, whose shops, galleries and restaurants offer a more multi-cultural atmosphere. Another area worth seeking out is the funky Quartier Latin, anchored by rue St.-Denis. Don't let bad weather keep you from hitting the shops. If it's rainy or cold, just retreat to Montreal's "underground city," shopping tunnels downtown where you'll find passageways lined with more than 1,000 stores.

Olympic Stadium: Check out the sights in Hochelaga-Maisonneauve, a neighborhood in eastern Montreal. This district played host to the 1976 Summer Olympics, and you can still tour the massive Olympic Stadium (4545 Avenue Pierre-De Coubertin; 514-252-4141). Take a ride to the top of the attached tower for views over the city.

Nature and Science: One intriguing attraction that's fun for kids and adults alike is the Biodome (4777 avenue Pierre-De Coubertin; 514-868-3000). At this zoo and environmental museum, you'll see animals and plants in five habitats: the tropical forest, the Laurentian forest, the Gulf of St Lawrence, the Labrador Coast and the Sub-Antarctic Islands. (The penguins are a fan favorite.) Also nearby are the lovely Botanical Gardens (4010 rue Sherbrooke Est.; 514-872-1400) and the kid-friendly Insectarium (4581 rue Sherbrooke Est.; 514-872-1400). The Rio Tinto Alcan Planetarium (4801 Avenue Pierre-De Coubertin; 514-868-3000) is the fourth element of Canada's largest natural science museum cluster -- the Montreal Space for Life, which offers hands-on immersion.

Casino de Montreal: Test your luck at Casino de Montreal, one of the world's biggest. There's a dress code, though it's been relaxed in recent years to accommodate casual attire.
