Mackenzie Highway North — Fort Simpson to Wrigley via Checkpoint
Mackenzie Valley's loneliest corridor north.
Highway 1 north of Fort Simpson is one of the loneliest paved-and-gravel corridors in Canada’s northwest, running roughly 220 km to Wrigley along the eastern bank of the Mackenzie River through unbroken boreal forest and muskeg. The road passes through the tiny fuel stop at Checkpoint — the only services between Fort Simpson and Wrigley — and skirts the edge of the Mackenzie Mountains foothills where the river valley opens into massive braided channels visible from pullouts above the tree line. Spring breakup can leave sections of gravel severely frost-heaved and saturated, and the last stretch into Wrigley drops into low-lying river flats prone to seasonal flooding.
This is a legitimate overland drive rather than a technical 4×4 challenge — most of it is driveable in a stock high-clearance 2WD, but frost heaves and soft shoulders in spring demand respect and slow speeds. Fuel up in Fort Simpson and again at Checkpoint if it’s open; Wrigley has no guaranteed fuel. Cell service disappears completely north of Fort Simpson. A satellite communicator is non-negotiable. Best window is July through September when the road is dry and the Mackenzie River scenery is at its most dramatic. No permit required.

Frequently asked questions
Can a stock truck or SUV handle this route, or do I need a lifted rig?
A high-clearance 2WD or stock 4WD truck handles it fine in dry summer conditions. The dirt and gravel surface is rough but not technical — your bigger concern is carrying spares and fuel, not ground clearance.
When does this road become impassable or risky?
Spring thaw (roughly April–June) turns sections to deep mud and can make the route genuinely impassable. July through September is the reliable window. Early fall can bring snow, and winter travel is possible but requires full cold-weather expedition prep — this is not a casual winter drive.
Do I need any permits or fees to drive this route?
No permits or fees required to drive the highway itself. It's a public territorial road managed by the GNWT. Check current highway conditions at inf.gov.nt.ca before you leave — road closures and restrictions get posted there.
What's the hardest or most committing part of this stretch?
There's no single gnarly obstacle — the commitment is the remoteness. The 137-mile corridor between Fort Simpson and Wrigley has zero services, no cell service, and minimal traffic. A mechanical breakdown here means a long wait. Carry a spare tire, recovery gear, and a satellite communicator.
How much fuel do I need, and where can I fill up?
Fuel up fully in Fort Simpson before you leave — there is no fuel available on the route until Wrigley, and Wrigley's fuel availability is not guaranteed. At 137 miles one-way, plan for well over 200 miles of range to give yourself a real buffer, especially if your rig is thirsty.
