Winnipeg River Road — Lac du Bonnet to Seven Sisters Falls Hydro Corridor
Shield granite, hydro history, and zero crowds.
The Winnipeg River corridor east of Lac du Bonnet is one of those Manitoba runs that doesn’t get talked about enough. Gravel and dirt resource roads trace the river’s east bank through Precambrian granite, thick boreal forest, and past the old Seven Sisters Falls hydroelectric dam — a structure that’s been generating power since 1931. The route threads through Manitoba Hydro access corridors and provincial crown land, crossing several seasonal creek drainages that turn sloppy after rain. Watch for the unmarked turnoffs near Pinawa that connect to the old Pinawa Dam Provincial Heritage Park access — one of the most photogenic ghost-infrastructure sites in the province.
This is a high-clearance route, not a rock-crawler, but you’ll want a proper 4WD truck when the clay sections get wet — and they will. Mud tires help significantly in spring and fall. Best run late summer through early fall when creek levels are down and the ground has firmed. Fuel up in Lac du Bonnet; there’s nothing reliable between there and Seven Sisters Falls. Cell service drops out hard once you’re in the granite. No permit required for the crown land sections. What you get is a genuinely lonely river corridor with jaw-dropping Canadian Shield scenery and almost nobody else on it.

Frequently asked questions
Can a stock 4Runner or Wrangler run this trail without modifications?
Yes — a stock 4WD vehicle with decent ground clearance handles this route fine under normal summer conditions. Lifted rigs aren't required, but you'll want all-terrain tires and a skid plate isn't a bad idea on the granite sections.
When does this trail typically open and close for the season?
July through October is the reliable window. Spring melt turns the dirt sections into a mess well into June, and freeze-thaw in November can make water crossings unpredictable. Don't push the shoulder seasons without checking recent conditions locally.
Do you need a permit to run this route or camp along it?
No formal permit is required for travel on this Crown Land corridor. Dispersed camping is allowed on Manitoba Crown Lands, but portions adjacent to Manitoba Hydro infrastructure may have restrictions — stay off fenced or posted hydro property and you're fine.
What's the hardest section and what should I actually expect?
The roughest stretches are the exposed granite shelf sections where the trail narrows and surface rock can be uneven and tippy at low speed. Nothing extreme, but a moment of inattention can put a rocker panel on granite — pick your line and don't rush it.
How far is it to the nearest fuel and should I top up before leaving Lac du Bonnet?
Yes, top up in Lac du Bonnet before you leave — there's no fuel along the 66 km route, and Seven Sisters Falls is a small community with no guarantee of a pump being open. Carry a spare jerry can if your tank is under 60L.
