Mackenzie Highway — High Level to Fort Simpson
Bison, boreal, and 200 km fuel gaps.
Highway 1 — the Mackenzie Highway — crosses from High Level, Alberta into the Northwest Territories and runs northwest to Fort Simpson on a broad tongue of land between the Liard and Mackenzie rivers. It’s not a technical trail, but don’t let the designation fool you: stretches of frost-heaved gravel, wandering bison on the road at dawn, zero cell service, and fuel stops spaced 200+ kilometres apart make this a route that demands preparation. The Lady Evelyn Falls territorial campground and the crossing at the Liard River ferry (seasonal) are the key waypoints. Nahanni National Park Reserve lies just to the west — Fort Simpson is the jumping-off point for floatplane access into the South Nahanni drainage.
This is a high-clearance gravel route passable by most capable rigs in summer, but washboard and soft shoulders after rain will punish low-clearance vehicles and trailers hard. Best season is June through September; spring breakup turns sections to mush. Carry at minimum 20 litres of extra fuel, a full-size spare, and a satellite communicator. Dispersed camping is available at territorial campgrounds along the corridor. Permits are not required, but self-sufficiency is non-negotiable this far north.

Frequently asked questions
Can a stock truck or SUV handle the Mackenzie Highway gravel, or do I need a lifted rig?
A stock high-clearance 2WD truck or SUV can manage the route under normal summer conditions, but 4WD is strongly recommended — washboard sections, soft shoulders, and unexpected rough patches are common on NWT gravel. A lifted rig isn't required, but decent all-terrain tires and a full-size spare (two is smarter) are non-negotiable on a 472 km stretch with no services.
When does the highway become impassable or seriously sketchy — early spring, late fall?
June through September is the reliable window. Spring breakup (April–May) turns sections to mud and can close the road entirely. By October, early snowfall and ice make conditions unpredictable and potentially dangerous, especially on gravel with no cell service and sparse traffic.
Do I need any permits or pay any fees to drive this route?
No permits or fees are required to drive the Mackenzie Highway itself — it's a public territorial highway maintained by the Government of the Northwest Territories. If you're crossing into Wood Buffalo National Park territory nearby, separate Parks Canada rules apply, but the highway corridor itself is free and open access.
What's the hardest or most demanding section of this route to drive?
There's no single technical obstacle, but the cumulative grind of 472 km of gravel — including corrugated washboard, loose rock, and dust or mud depending on conditions — is what breaks people. The stretch north of High Level toward Hay River junction sees the least maintenance traffic and can be the roughest; budget for reduced speeds (80 km/h or less) and fatigue management over multiple days.
How serious is the 200 km fuel gap — what's the actual plan for not running dry?
Dead serious. Between High Level, AB and Fort Simpson, NT, fuel availability is extremely limited and unreliable — some stops marked on older maps have closed. Carry enough jerry cans to cover at least 400 km of range before you leave High Level, top off at every confirmed open station, and verify current fuel availability at https://www.inf.gov.nt.ca before departure. Running out of fuel out here isn't an inconvenience — it's a multi-hour rescue situation.
