Lac Nairne, Saint-Irénée, Parc le Pélican, semi-Olympic pool: where to swim in Charlevoix, from beaches to lap lanes. A practical guide.
Visitors arriving in Charlevoix along Route 138 or 362 see the river stretching to the horizon, sandbars uncovered at low tide, and naturally assume they will swim there in summer. The reality is more nuanced: the Saint Lawrence at Charlevoix is too cold for real swimming — salt water, churned by tides and currents coming from the Saguenay, rarely rises above 15°C even in July. The region's true bathing spots are inland lakes. The smart approach in Charlevoix in summer is to use the river for walking and contemplation, and drive to the lakes when the plan is to get wet.
Why the river isn't really for swimming
At this stretch of the Saint Lawrence, the water is salt — tides push oceanic water all the way to Québec City — and cold. The Saguenay current, which joins the river at Tadoussac an hour and a half away, brings glacial water from the fjord. Water temperatures rarely break 13–15°C at the peak of summer. A few brave souls dip in for a minute as a stunt, but extended swimming is not realistic.
That does not diminish the value of the shoreline. Walking the low-tide beaches, looking at the river, picnicking on wet sand remain core activities of a summer stay. Our piece on the Saint Lawrence riverside walk covers several access points to the river that don't require swimming.
Lac Nairne and the Base de Plein Air (Saint-Aimé-des-Lacs)
Lac Nairne, in Saint-Aimé-des-Lacs, is probably the best swimming option for anyone staying near La Malbaie. The municipality runs the Base de Plein Air du Lac-Nairne, which combines a sand beach, picnic grounds, kayak and canoe rentals, and a campground. The lake's water warms up in June and stays comfortably swimmable from July through late August — a medium-depth lake, well sheltered from wind, with a supervised swimming area in high season.
The site is about twenty minutes from Cap-à-l'Aigle on Route 138 east, then Route 170 toward Saint-Aimé-des-Lacs. It works well as a half-day plan: swim and picnic, return via the scenic road through Clermont. For families, the spot combines bathing with gentle water sports — the lake is ideal for a first outing in a canoe or paddleboard. Our Charlevoix family activities guide covers other options along the same lines.
Saint-Irénée Beach and Parc le Pélican
For those who insist on the river, two places stand out.
The Saint-Irénée beach, about twenty minutes west of La Malbaie on Route 362, is one of the finest sand beaches on the lower Saint Lawrence. At low tide, the sand strip extends several hundred metres, dotted with a few pebbles. It is the right place for a walk, flying a kite, or simply settling in with a book facing the river. Swimming remains for the committed, but wading for a few minutes is pleasant at midsummer. The neighbouring village also hosts the Domaine Forget — see our piece on its summer festival.
Parc le Pélican, in La Malbaie itself, offers a long beach uncovered at low tide, more discreet and far less crowded than Saint-Irénée. It is more of a municipal park than a beach destination, but the place has its charm — especially in late afternoon, when the tide drops and low sun lights up the sandbars.
Other water spots in Charlevoix
The Baie-Saint-Paul wharf provides river access in a more urban setting — the town is right behind, with its galleries and restaurants. Swimming is occasional, but the walk and the sunset are worth the trip.
Active visitors will rather take to a craft. Our piece on kayak and water activities in Charlevoix details the best spots — river, lakes and rivers combined. And the Isle-aux-Coudres, reached by ferry from Saint-Joseph-de-la-Rive, has a few discreet beaches that islanders appreciate but tourists sometimes overlook.
For real swimming: the La Malbaie semi-Olympic pool
For visitors who want real swimming — measured in laps, not in dips — La Malbaie has a semi-Olympic indoor pool at its sports complex. It is the option that changes the math of a Charlevoix stay: those keeping to a morning training routine, or who simply want a few lengths before supper, can use the facility, which is open to the public year-round.

At the Le Littoral chalet: heated pool with Saint Lawrence River view
Alongside the public options, there is also the private pool at Le Littoral chalet to rent in Cap-à-l'Aigle — the property rents by the week, about ten minutes from the Saint-Irénée beach and Parc le Pélican. The outdoor pool is heated, 2.75 m × 6.40 m, with a direct view of the Saint Lawrence River. Water at 28°C, open June 1 to September 15, a wood deck around the basin, loungers and pool towels provided.
It is the right setup for family swimming: the pool is fully enclosed by a 120 cm safety wall for younger children, available at any hour of the stay, and paired with the panoramic view that gives every length its own quality. After a day at the lake and supper at the chalet, an evening swim in heated water facing the river is probably the best reason to stay in.
Practical: gear, tides, tips
For lake swimming, gear stays minimal: swimsuit, towel, sandals for the occasional rocky approach. At the Lac-Nairne base, beach chairs and umbrellas can be rented on site; for a picnic, bring a cooler since the village shops are a few minutes away.
On the river, always check the tide schedule before approaching the shore. The tidal range in Charlevoix is large — 5 to 6 metres at mid-tide — and the Saint-Irénée beach and Parc le Pélican beach look like two completely different places at high tide and low tide. The incoming tide rises quickly on flat sand; a walk started at low tide can find itself cut off from the shoreline if you linger. The Pointe-au-Pic tide station in La Malbaie publishes up-to-date predictions for free on the Fisheries and Oceans Canada website — bookmark it before any outing to the beaches.
To plan the full stay, our things to do in Charlevoix guide collects the other activities worth considering. The best approach in high season is to combine: a morning at Lac Nairne for actual swimming, a picnic on the grass with bread from Boulangerie de Comporté, then a return drive along Route 362 with a sunset stop at Saint-Irénée beach for a walk on the sand once the heat has eased. The day composes itself around the water, without forcing anything.
