Campgrounds and RV parks near Longueuil, QC

The standout outdoor draw is Parc national des Îles-de-Boucherville, a Sépaq park in the St. Lawrence with flat cycling and hiking trails, channels for canoeing, sea kayaking, pedal-boating and stand-up paddleboarding, and a cable ferry linking the islands. Wildlife watching includes white-tailed deer, beaver, waterfowl, and a wide variety of river fish. Guided discovery activities, an interpretation centre on Île Sainte-Marguerite, and the lookout tower on the Île-aux-Raisins trail face the Montreal skyline. From Longueuil, the Yellow Line metro and the REM light-rail link directly to downtown Montreal, Old Montreal, Mount Royal, and the Plateau. The Richelieu River valley, Parc national du Mont-Saint-Bruno, and the historic Chambly canal sit a short drive south and east.

The RV season on the South Shore is tightly bound to the seasons. Most private campgrounds, including Montreal South KOA Journey, open around the start of May and close in mid-to-late October. July and August are the busiest months: warm days, long daylight, festival season in Montreal, and the highest demand for serviced sites. Reserve well in advance for those months and for any weekend tied to a Montreal festival or Grand Prix event. Late spring and early fall are quieter and cooler, with crisp nights and active wildlife on the Boucherville islands. Fall colour on the South Shore typically peaks from late September into mid-October. Winter conditions are harsh: snow normally covers the ground from late November to mid-March, and most RV parks are closed. Parc national des Îles-de-Boucherville stays open year-round for day use and winter activities such as snowshoeing and cross-country skiing on its flat trails, but RV camping in the Molson sector is a warm-season offering.

Expect a mix of urban-adjacent and island settings rather than backcountry wilderness. The Molson RV sector at Parc national des Îles-de-Boucherville is an open, unwooded area on an asphalt surface, designed for trailers and motorhomes and recommended for self-sufficient visitors since the washroom block sits about 500 metres from the sites. The sector has 30-amp electrical service, water outlets, and a dump station, with showers in the nearby sanitary block. Montreal South KOA Journey offers pull-through sites, 30- and 50-amp service, water, sewer, Wi-Fi, a seasonal pool, laundry, and a playground, with bilingual French and English staff. French is the working language across the region, though English is widely understood at tourist-facing campgrounds. Bridge traffic into Montreal is heaviest at rush hour.
