Nahanni Butte to Naha Dehé Wilderness Road — South Nahanni River Confluence
The sentinel butte at the edge of Nahanni country.
The road to Nahanni Butte starts at a barge crossing on the Liard River near Fort Simpson and punches roughly 30 km southwest through black spruce muskeg and river flats to the small Dene community at the base of Nahanni Butte — a 700-metre flat-topped sentinel that dominates the skyline. This is the gateway approach for those running boats up the South Nahanni toward Virginia Falls, and the overlanding approach gives you a genuine sense of just how remote and wild this corner of the NWT actually is. Soft shoulders, mud wallows after rain, and one low-lying creek crossing keep it real.
A stock 4WD with good all-terrain tires handles this in dry conditions, but after significant rainfall it earns a difficult rating fast — the muskeg sections turn greasy and will swallow unprepared rigs. No fuel beyond Fort Simpson, so top off before you leave. Cell service disappears completely once you leave the highway. Dispersed camping is possible along the route but respect the community’s traditional lands. Best run late June through August when the frost-heaved track has dried out. This one rewards patience and respect — it’s not a sport run, it’s a journey to somewhere that feels genuinely forgotten.

Frequently asked questions
Can a stock 4Runner or Land Cruiser handle this trail without modifications?
Yes, a stock 4WD high-clearance vehicle is the minimum and will manage the dirt and gravel track under normal summer conditions. Soft ground after rain can get greasy, so locking diffs or AT tires are a real advantage out here.
When is this road actually passable — and is it a death trap in spring?
June through August is the reliable window. Spring breakup turns the ground to soup, and early season water crossings can run significantly higher than summer levels. Don't push it before mid-June unless you have local intel.
Do I need a permit to drive through Nahanni Butte or access this route?
The road passes through Nahanni Butte Dene Band territory, so it's worth contacting the band ahead of time out of respect and to confirm current access conditions. There's no formal paid permit system for the road itself, but this is an Indigenous community — don't just roll through without acknowledgment.
What's the hardest part of this route and what should I actually be worried about?
The water crossings are the honest variable — depth and current shift with rainfall and snowmelt, and there's no bailout infrastructure once you're committed. The remoteness is the real difficulty multiplier: a breakdown here means a very long wait with zero cell service.
Is there any gas or resupply between Fort Simpson and the trail, and how much range do I need?
Fort Simpson is your last fuel stop — full stop. The round trip is roughly 40 miles of trail alone, but the drive from Fort Simpson adds significant distance, so plan for at least 150–200 miles of fuel buffer minimum. Carry extra; the nearest help is not close.
