Getting oriented in Montréal is remarkably easy. The airport is only 23km (14 miles) away at most, and once you're in town, the Métro (subway) is fast and efficient. Walking, of course, is the best way to enjoy and appreciate this vigorous, multidimensional city. Take it in, neighborhood by neighborhood.
The main tourist center for visitors in downtown Montréal is the large Infotouriste Centre, at 1255 rue Peel (tel. 877/266-5687 or 514/873-2015; Métro: Peel). It's open daily and the bilingual staff can provide suggestions for accommodations, dining, car rentals, and attractions.
In Vieux-Montréal, there's a small Tourist Information Office at 174 rue Notre-Dame est, at the corner of Place Jacques-Cartier (Métro: Champ-de-Mars). It's open daily in warmer months, Wednesday through Sunday in winter, and proffers brochures, maps, and a helpful staff.
