McArthur Game Sanctuary Road — Teslin to Swift River Highlands
Boreal mud and moose past Teslin.
Branching north off the Alaska Highway near Teslin, this seldom-travelled resource road pushes deep into the Swift River uplands — terrain that most Yukoners know by reputation rather than tire tracks. The route follows old mineral exploration corridors through dense spruce forest, crossing the Jennings River tributary network where beaver-dammed drainages create soft shoulders and surprise water crossings that catch overconfident rigs flat-footed. By the time you reach the elevated benches above the Swift River valley, the view across the St. Cyr Range makes the mud-splattered windshield worth every ounce of it.
This is an honest high-clearance gravel run with sections of unmaintained cat road that demand a capable rig — a lifted truck with good all-terrain rubber is the minimum, and a locker helps when the clay-based soil gets wet. No fuel beyond Teslin, so top up. Cell service drops to zero within 20 km of the highway. Best run July through mid-September before the seasonal rains turn the clay sections into a skating rink. No formal permit required, but bear spray is mandatory common sense. Dispersed camping is available throughout — find a high spot with drainage.

Frequently asked questions
Can a lifted Tacoma or 4Runner handle this trail, or do I need something more serious?
A high-clearance 4WD with a proper skid package is the minimum — a stock lifted Tacoma or 4Runner will work if the driver knows what they're doing. The mud sections and rutted stretches after rain can swallow low-clearance rigs whole, and there's no recovery service within range.
When does the trail actually become passable, and is it a mud pit all summer?
July through September is the realistic window — snowmelt keeps it rough into June and early frosts can hit by late September. Mid-July to August is the sweet spot, though a stretch of rain can turn the boreal clay sections into a serious slog at any point in the season.
Do I need a permit to drive through the McArthur Game Sanctuary?
No permit is required for vehicle travel through the sanctuary, but it is managed by the Yukon Department of Environment and hunting regulations within the sanctuary are strict — know the rules before you bring firearms. No fees as of last check.
What's the hardest section of this trail and what exactly makes it difficult?
The mid-route lowland bog sections are where most rigs get into trouble — deep wheel-sucking mud, minimal drainage, and no detour options. Add in the unbridged water crossings, which can run fast and thigh-deep depending on rainfall, and you've got a trail that earns its difficulty rating honestly.
There's zero cell service — how far is it to a gas station if something goes wrong?
Teslin on the Alaska Highway is your last fuel stop before you head in, and Swift River Lodge (roughly at the northern end) sometimes has fuel but do not count on it — call ahead or treat it as if it doesn't exist. Carry enough fuel to run the full 68 miles plus a reserve for recovery situations.
