Slave River Road — Fort Smith to Fort Resolution via Pine Lake Access
Bison country deep in Wood Buffalo's NWT heart.
Fort Smith sits on the banks of the Slave River at the Alberta border, and it’s the southern gateway into Wood Buffalo National Park — the largest national park in Canada and one of the last places on earth where free-roaming wood bison exist in wild herds. The road network south and west of Fort Smith includes the Pine Lake Road, a maintained gravel route dropping 60 km into the park interior to Pine Lake campground, plus rougher tracks pushing into the boreal lowlands toward the salt plains and bison range. The salt plains near Pine Lake are a genuinely surreal landscape — mineral deposits create white flats that look completely out of place in the northern forest. Bison wander freely across roads here, and that is not a figure of speech.
Most of the Pine Lake Road is manageable in a stock SUV when dry, but the backcountry tracks branching off it demand high clearance and 4WD — muskeg is always close in Wood Buffalo. A Parks Canada entry permit is required. Fuel in Fort Smith before heading in; there’s nothing inside the park. Late June through September is the practical window — spring thaw makes the soft sections genuinely impassable. The route toward Fort Resolution adds distance and requires checking current road status with the GNWT, as portions are seasonal. What you get is bison, wolves, boreal silence, and one of the most underrated park interiors on the continent.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this route, or do I need a lift?
A stock high-clearance 4WD is the minimum — a bone-stock Tacoma or 4Runner will manage under dry conditions. After rain, soft clay sections can get punishing, so lockers or at least good all-terrain tires are worth having before you commit.
When does the road typically open and close each year?
June through September is the reliable window. Spring breakup leaves the clay surface a mess well into May, and early snowfall can shut things down by October. Check with Parks Canada's Fort Smith office before departing — conditions change fast up here.
Do I need a permit to drive through Wood Buffalo National Park?
Yes — a valid Parks Canada entry permit is required. You can buy a daily or annual pass through Parks Canada's website or at the Fort Smith visitor centre before you head out.
What's the hardest section of the route and what should I actually expect?
The roughest stretches tend to be the low-lying clay flats between Fort Smith and Pine Lake, where standing water and ruts can develop quickly after rain. It's rated Moderate but wet clay is deceptively nasty — if it's been raining for a day or more, those sections can swallow a vehicle that's moving too slow.
There's no cell service for 99 miles — where do I fuel up and is there any water along the route?
Fuel up completely in Fort Smith before departure; there are no services between there and Fort Resolution. Pine Lake has a staffed Parks Canada campground with potable water mid-route, but treat any other sources you pull from along the way.
