Deh Cho Route — Fort Providence to Fort Simpson via Mackenzie Highway Backcountry Spurs
Big River country — bison, boreal, and zero crowds.
The Deh Cho — ‘Big River’ in Dene — has been a travel corridor for thousands of years, and the gravel spur roads branching off Highway 1 between Fort Providence and Fort Simpson give you a taste of that heritage. The main highway is gravel most of the way and rough enough to punish an unprepared truck, but the real rewards come off the beaten track: spur roads dropping toward the Mackenzie River flats at spots like Mills Lake and the Jean Marie River confluence, where wood bison graze the meadows and the river stretches a kilometre wide. The Sambaa K’e (Trout Lake) spur off Highway 1 near Checkpoint adds serious remoteness to the equation — 90km of rough track each way into Dehcho First Nations territory.
This is a Moderate to Difficult route depending on how deep into the spurs you push. The main highway is manageable for a stock 4WD high-clearance truck but the river-access spurs require real clearance and recovery gear. The shoulder seasons — May and October — can turn the clay-based spur roads into wheel-swallowing bogs. Summer is the go-to season but bring your A-game for mosquitoes from June through August. Fuel up hard in Fort Providence and again in Fort Simpson because there’s nothing between them. No permits required, dispersed camping available on Crown land off the spurs.

Frequently asked questions
What's the minimum rig to run this route without getting into trouble?
4WD with high clearance is the floor — spur roads off Highway 1 get soft, rutted, and muddy, especially after rain. A stock Tacoma or 4Runner with all-terrains will handle it, but a lifted rig with lockers gives you real margin out here. A 2WD truck on the main highway sections is fine, but don't touch the spurs in one.
Can you run this in early June or does the ground need to dry out first?
Early June is risky — spring breakup leaves the spur roads genuinely impassable in places, and the NWT highway system deals with serious frost heave and mud through late May into June. Late June through August is the reliable window; September works but watch for early snowfall above 1,000 ft. Check highway conditions at inf.gov.nt.ca before you leave Fort Providence.
Do you need permits to camp or drive the spur roads through Dehcho First Nations territory?
No permit is required to travel Highway 1 or most spur roads, but you're passing through Dehcho First Nations traditional territory the entire route — respect closures and signage. Dispersed camping is allowed on Crown land but confirm you're not on First Nations land before setting up; signage is sparse so when in doubt, ask in Fort Providence or Fort Simpson.
What's the hardest section and what actually makes it difficult?
The boreal spur roads dropping toward the Mackenzie River flats are the crux — low-lying, poorly drained, and they deteriorate fast after any rain. Expect deep ruts, exposed clay, and sections where the road essentially becomes a channel. It's not technical rock crawling, it's the slow grind of soft ground that eats traction and punishes low-clearance rigs.
How much fuel range do you need? Are there reliable fill-up points between Fort Providence and Fort Simpson?
Fort Providence and Fort Simpson both have fuel — but that's 220 miles with limited options in between. Hay River is a reasonable detour, and there's a small station at Enterprise, but don't count on anything being open or stocked on the spurs. Carry a minimum 10-gallon auxiliary supply; 15 gallons is smarter given the spur road exploration and the remoteness of this corridor.
