Liard Trail — Fort Simpson to Nahanni Butte via the Liard River Valley and Mackenzie Mountains Fringe
End of the road — literally — in Canada's subarctic.
The Liard Trail (NWT Highway 7) runs southwest from Fort Simpson along the Liard River toward the Mackenzie Mountains, terminating at the tiny community of Nahanni Butte — a village of fewer than 100 people sitting at the confluence of the South Nahanni and Liard rivers. This is not a loop road and there’s no bridge at the end; a ferry or floatplane gets you the final stretch in season. The road itself is raw northern gravel: narrow, soft-shouldered, heavily rutted after rain, and lined with boreal spruce and muskeg that makes recovery interesting if you slide off the crown. The Liard cuts close in places and the valley views into the outer Mackenzie ranges are genuinely stunning — especially in late August when the tundra hillsides go orange.
High clearance is essential; a true 4WD with AT tires handles normal dry conditions but mud season (May and after rain) turns this into a proper slog. Fuel at Fort Simpson before you leave — there is nothing at the far end. The ferry to Nahanni Butte operates June through October; after freeze-up a winter ice road sometimes connects. No permit required for the road itself, though Nahanni National Park Reserve requires registration for river access beyond the community. Best visited July through early September. Cell service drops to zero within 20 km of Fort Simpson and stays there. This is genuine edge-of-the-map driving in one of North America’s most overlooked wild corridors.

Frequently asked questions
Can a stock high-clearance 2WD truck handle the Liard Trail, or do I need 4WD?
A high-clearance 2WD can make it in dry conditions, but the surface turns to slick clay mud after rain and 4WD becomes non-negotiable. If there's been any precipitation in the days before your run, don't attempt it without 4WD — the approach to Nahanni Butte gets greasy fast and recovery out there is a serious problem.
When does the Liard Trail actually open and close each year?
The trail typically opens in late June or early July once spring breakup mud stabilizes, and closes in October as freeze-up begins. July through September is the reliable window — shoulder months can have the road closed entirely due to condition. Always check current status with GNWT Infrastructure before heading out, as closures happen with little warning.
Do I need a permit to drive the Liard Trail or camp along it?
No permit is required to drive Highway 7 or camp along the route itself — it's a public territorial highway with dispersed camping allowed. If you're planning to enter Nahanni National Park Reserve from Nahanni Butte, Parks Canada does require advance registration and trip planning through their office.
What's the hardest section of the trail and what should I actually expect?
The trail doesn't have one dramatic obstacle — the challenge is cumulative: 107 miles of unmaintained dirt with washouts, soft shoulders, and zero infrastructure. After rain, the clay sections near the Nahanni Butte end become the most treacherous, with deep ruts and side-slope mud that can catch you off guard. Plan for slow speeds and carry a full recovery kit.
Where's the last fuel stop before driving the Liard Trail, and how far is the round trip?
Fort Simpson is your last fuel — full stop. There is zero fuel available on the trail or at Nahanni Butte. The round trip from Fort Simpson is roughly 214 miles (344 km), so calculate your range conservatively and carry a jerry can if your rig drinks fuel in low-gear mud crawling.
