Chemin Grandes-Bergeronnes — Saguenay–St. Lawrence Marine Park Plateau Road
St. Lawrence plateau above the beluga country.
The north shore of the St. Lawrence between Tadoussac and Sacré-Cœur is dominated by the dramatic plateau that drops straight into the estuary, and the back road network above Grandes-Bergeronnes is one of the few places you can get a 4×4 up into that terrain without a chainsaw permit. The main track climbs steeply from the village past the Pointe-des-Roches beluga observation area, then threads inland through second-growth boreal forest on a mix of crushed gravel and exposed bedrock ledges — classic Canadian Shield stuff. The high point near Cap-de-Bon-Désir gives an unobstructed view down onto the St. Lawrence shipping lane and the Saguenay fjord mouth. Watch for logging truck traffic on weekday mornings; they own these roads and they know it.
High-clearance is mandatory; 4WD with all-terrains is the practical minimum. No permits required but check with the local municipality for seasonal road closures — spring thaw usually locks the upper sections until late May. The route is doable as a long day from Tadoussac but a night camped on the plateau above the estuary is worth it if you can find a flat pull-off. No services beyond Grandes-Bergeronnes itself; fuel and supplies in Tadoussac or Baie-Sainte-Catherine. Cell service is spotty at best once you gain elevation.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this without modifications?
Yes, a stock high-clearance 4WD like a Tacoma or 4Runner is the minimum you want here. The mixed rock and gravel surface has some rough washboard and embedded boulders, but nothing requiring a lift — just don't try it in a crossover or 2WD truck.
When does the trail typically open and close for the season?
June through October is the reliable window. Spring melt can leave the plateau road soft and rutted well into May, and early snowfall can hit the plateau in October. Check with the Municipalité des Bergeronnes before heading up outside that window.
Do you need a permit to drive this road or camp along it?
No permit is required to drive the Chemin Grandes-Bergeronnes plateau road itself, which falls under municipal jurisdiction. If you wander into the adjacent Saguenay–St. Lawrence Marine Park boundaries, Parks Canada rules apply — know where you are.
What's the hardest section and what should I actually expect?
The roughest stretch is the upper plateau where the road narrows and rock outcroppings push into the track — low-range is useful here, not mandatory. Biggest real hazard is loose gravel on descents toward Sacré-Cœur, so keep speed down and watch for logging trucks if the cuts are active.
How far is the nearest gas station and is there water along the trail?
Fill up in Grandes-Bergeronnes before you head out — it's a small town but has fuel. There's no reliable potable water on the plateau, so carry what you need for 1-2 days; cell service is spotty at best up there, so don't count on being able to call for help if you run dry.
