A realistic Montreal-to-Tadoussac driving itinerary with the free ferry, overnight stops, the dunes and what we would do differently.
Driving from Montreal to Tadoussac looks straightforward on a map. In reality, the trip covers about 480 kilometres, includes a ferry, possible queues and one of Quebec’s most scenic regions asking you to slow down.
We made this trip as a family in August 2020. We left Montreal late on Friday, slept in Quebec City and continued to Tadoussac the next day. It worked, but today I would give the route more time.

Quick answer: allow at least three days, preferably four or five. The Baie-Sainte-Catherine–Tadoussac ferry is free, but do not treat its schedule as a guaranteed connection. Book lodging and cruises early in high season.
Information checked on August 9, 2026. Ferry schedules, roadwork and driving conditions can change.
Montreal to Tadoussac: distance and realistic travel time
| Segment | Approximate distance | Time without stops |
|---|---|---|
| Montreal to Quebec City | 255 km | 3 hours |
| Quebec City to Baie-Sainte-Catherine | 210 km | 3 hours |
| Ferry to Tadoussac | About 1.5 km | 10 minutes on the water, plus waiting |
| Montreal to Tadoussac | 480 km | 6 to 7 hours, excluding stops |
GPS time is optimistic. Add Montreal traffic, fuel, meals, viewpoints and the ferry queue. On a sunny August Saturday, plan for seven to eight hours. A same-day return is exhausting, particularly with children.
The three-day route we took
Friday: Montreal to Quebec City
We left around 5 p.m. Sleeping in Quebec City split the long drive, but rush hour made the first leg slower. Leaving before 3 p.m. or the next morning would be more comfortable.
Saturday: Quebec City, Charlevoix, ferry and Tadoussac
Route 138 follows the north shore of the St. Lawrence through Charlevoix. Its hills, curves and river views are part of the trip, not dead time between attractions.
Charlevoix’s viewpoints are a good reason not to plan every minute of the drive.
At Baie-Sainte-Catherine, cars line up for the crossing. Ordinary vehicles do not need a reservation.
Sunday: returning through Quebec
We returned on the same road and stopped near Quebec City. It was possible, but Tadoussac felt squeezed between long drives. Today I would add a night for the village, dunes and weather flexibility.
How the Tadoussac ferry works

The ferry connects Route 138 across the Saguenay River and is free, according to the Société des traversiers du Québec.
- No ticket is required for an ordinary car.
- The crossing is short, but waiting times vary.
- Summer weekends and holidays can produce queues.
- Check the official STQ schedule the day before and before departure.
Do not book a cruise against your GPS arrival time. I would keep a 60-to-90-minute buffer.
A better four or five-day itinerary
Day 1: Montreal to Quebec City
Leave in the morning, have lunch in Quebec City and sleep there or continue to Baie-Saint-Paul.
Day 2: Charlevoix and Tadoussac
Stop at viewpoints, cross the ferry without rushing and walk through Tadoussac. Visit the dunes late in the afternoon if you still have energy.
The Tadoussac dunes deserve their own stop
The dunes are about ten minutes by car from the marina and were one of our trip’s surprises. From below they look like a wall of sand framed by forest. The Canadian landscape has a completely different scale from the dunes I knew in northeastern Brazil, and the cold water quickly ends any tropical illusion.
The tiny people on the sand show how high the climb really is.
Allow two or three hours if you want to reach the beach, preferably near low tide. Going down is easy; climbing back through soft sand is much harder than it looks.
At the bottom, we found a small waterfall reaching the beach. The water was extremely cold, but Alice still went in.
The waterfall below the dunes was an unexpected discovery.
Alice and I after the descent, with the climb back still ahead of us.
Bring water, sand-friendly footwear and do not schedule a whale cruise immediately afterward.
Day 3: whale watching
Book a morning or late-afternoon departure and keep the rest of the day flexible. Visit the CIMM and a coastal trail.
Day 4: Route des Baleines or an easy return
With four days, start back. With five, continue to Les Escoumins for shore observation.
Day 5: Quebec City to Montreal
Splitting the return avoids ending a memorable trip with six consecutive hours behind the wheel.
Where to stay
Tadoussac is our first choice because you wake near the pier and can explore on foot. Baie-Sainte-Catherine is practical if your cruise leaves from that side. Quebec City is an excellent stopover, but it is not a nearby base: a return trip from there still exceeds 400 kilometres.
Car or motorhome?
A regular car is simplest. Route 138 is paved and does not require a special vehicle. A motorhome adds flexibility but demands campsite planning; popular sites fill quickly and overnight parking is not allowed everywhere.
What the road trip costs
| Item | How to estimate it |
|---|---|
| Fuel | About 1,000 to 1,200 km round trip |
| Lodging | Two to four nights |
| Ferry | Free on this crossing |
| Whale tour | AML Zodiac from CAD 99.99 before tax in 2026 |
| Food | Pack snacks and budget for tourist-area meals |
| Parking | Confirm with your lodging and operator |
Mistakes we would avoid today
- Planning every segment to the minute.
- Sleeping far away before the cruise.
- Underestimating cold air over the water.
- Treating the ferry like an airline connection.
- Visiting only for the whales and missing Charlevoix, the fjord and dunes.
Our verdict
Montreal to Tadoussac is an excellent road trip when it stops being a race to the pier. If I repeated it today, I would allow four days, spend two nights near Tadoussac and leave a flexible period around the cruise.
