Le Vieux-Longueuil
Introduction
Le Vieux-Longueuil is a borough of the city of Longueuil, and it is the old quarter that gives the area its name.
Getting around
Your anchor for getting around Le Vieux-Longueuil is Terminus Longueuil, the central bus terminal, which also houses the Longueuil–Université-de-Sherbrooke metro station on the Yellow line (Line 4) — bus and metro connections are made under one roof. The Yellow line runs beneath the St. Lawrence River and includes a stop at Île Sainte-Hélène, so it's a convenient way to reach the river islands as well as downtown Montreal. Most RTL public buses depart from and arrive at Terminus Longueuil, making it the hub for local travel; from anywhere in the borough, your likely route is a local bus to the terminus followed by a transfer to the metro or another bus. Fares are integrated across the region: a Tram 3 fare covers public transit in Laval, Montreal and Longueuil (except St-Bruno-de-Montarville, which requires Tram 5), while a Train 3 fare covers only the commuter train network. Metro fares are set by the STM and are separate from local bus fares, so buy the appropriate fare for the network you're using.
For commuter rail, Longueuil is served by the St-Lambert and St-Hubert stations on the AMT's Mont-St-Hilaire line, useful if you're arriving from or heading along that corridor rather than downtown Montreal; Via Rail also stops at Longueuil-Saint-Hubert, giving an intercity rail option. Orléans Express runs intercity buses from Quebec City (Ste-Foy) if you're combining your visit with a trip elsewhere in the province. From Montréal–Trudeau airport, take the 747 bus to Downtown Montreal, then transfer to the Yellow line to Longueuil–Université-de-Sherbrooke; the 747 fare includes use of the STM network, including the metro, for the rest of the day. On foot, the historic core around Rue Saint-Charles is compact and realistic for moving between shops, restaurants and nearby points of interest, but destinations outside the old core — including the commuter rail stations — are spread out enough that you'll likely want a bus or car. Taxis are best arranged around Terminus Longueuil and the Rue Saint-Charles area.
Three days in Le Vieux-Longueuil
Day one: Start in Le Vieux, the old quarter of Longueuil, and get your bearings on foot before heading to Terminus Longueuil, the hub where the Yellow Line, RTL buses and the Réseau de transport de Longueuil network converge. From there, cross under the St. Lawrence River to Montreal on the Yellow Line, with Sainte-Hélène island and the river itself shaping the views. Keep the day simple: walk Le Vieux, ride the Metro, and let the STM and RTL systems do the work of moving you between the two banks.
Day two: Use the Yellow Line again, this time toward Downtown Montreal, and connect with the STM network for the day. If you are arriving by train, note that Via Rail, AMT and the Metro all feed into the same central web, so you can link a Montreal morning with a Longueuil afternoon without much fuss. Return to Le Vieux in the evening for a slower pace along the river.
Day three: Take the RTL buses from Terminus Longueuil to explore the wider South Shore, or head out toward Mont Saint-Hilaire and Mont Bruno for a change of scenery. Fares on the RTL and STM are separate systems, so plan your crossings accordingly. End back in Le Vieux, where the old quarter's streets give you a quiet close to three days split between Longueuil and Montreal.
