The Dempster Highway runs 736 km (457 miles) from the Klondike Highway near Dawson City, Yukon, to Inuvik in the Northwest Territories, and it is unpaved for effectively its entire length. Two numbers decide whether you should attempt it. The first is 369 — that is how many kilometres you ride from the start before you reach Eagle Plains, the first place with fuel. The second is 736, because after Eagle Plains there are exactly two more settlements on the whole road. This is not a scenic detour. It is a gravel highway across the Ogilvie and Richardson mountains and over the Arctic Circle, with two river crossings that depend on ferries in summer and ice bridges in winter, and it needs a bike and a set of tyres chosen for it.
What the road is
The Dempster is Yukon Highway 5 for its first 465 km (289 miles) and Northwest Territories Highway 8 for the remaining 271 km (168 miles). It begins 40 km (25 miles) east of Dawson City on the Klondike Highway and runs north-north-east to Inuvik on the Mackenzie River delta. There are no highway or major road intersections along its entire route — you turn on at one end and off at the other.
It exists because of oil exploration and Arctic sovereignty rather than tourism. Survey work started in 1958, construction began at Dawson City in January 1959, and it stalled in 1962 after only 115 km of roadbed when the Eagle Plains oil discovery proved commercially worthless. Work resumed in 1970 after the American Prudhoe Bay discovery gave Ottawa a reason to assert a presence in the north. The final section was completed in 1978 at a cost of $132 million, and the highway officially opened on 18 August 1979 at Flat Creek. It is named after Corporal William Dempster of the North-West Mounted Police, who in March 1911 led the patrol that found the bodies of Inspector Fitzgerald's lost patrol between Fort McPherson and Dawson City.
The construction detail that matters most to riders is the surface. The road had to be built so that heat from the highway would not melt the permafrost underneath, so it sits on a gravel berm between 1.2 and 2.4 m (roughly 4 to 8 ft) thick. That berm is the road. There is no asphalt to lay on top of it without defeating the point of the design, which is why the Dempster is gravel and will stay gravel.

The supply gaps, which are the whole planning problem
Read these distances as fuel legs, because that is what they are.
Start to Eagle Plains: 369 km. Eagle Plains at km 369 is the first available service on the highway, and it is the only place between Tombstone Territorial Park and Fort McPherson that offers fuel and accommodation at all. If you start from Dawson City rather than the junction, add the 40 km back to town and you are looking at roughly 409 km between fills. On gravel, into wind, on a loaded bike, that is a serious leg. Riders who do this routinely carry additional fuel rather than trusting a range figure calculated on tarmac.
Eagle Plains to Fort McPherson: 181 km. The Arctic Circle marker sits at km 405, the Yukon–Northwest Territories border at km 465, and the Peel River crossing at km 539. Fort McPherson at km 550 is described in the official route listing as the second and last available services on the highway.
Fort McPherson to Inuvik: 186 km. With the Mackenzie River crossing at Tsiigehtchic at km 608 in the middle of it.
One more oddity worth knowing: the Wiley Aerodrome at km 391 uses a portion of the highway as its runway.
Bike and tyres, which is not an optional discussion here
The Dempster is a maintained gravel highway, not a technical off-road route, and it is regularly driven by ordinary cars. That fact misleads people. On two wheels the surface changes everything, and the sensible setup is not the same as for a paved tour.
Bike. A mid or large adventure bike with long-travel suspension, a decent fuel range and enough ground clearance for loose surface and washboard is the natural choice. A dual-sport is equally fine and lighter to pick up. Big road tourers do get ridden up the Dempster, but every kilogram counts differently on gravel than on tarmac, and a heavy machine on a loose crown is unforgiving when a truck comes past in the other direction.
Tyres. Street tyres are the wrong choice. The realistic range is a 50/50 or 80/20 adventure tyre with a robust carcass, and puncture resistance matters more than tread pattern. The gravel used on northern roads includes sharp shale that cuts sidewalls, and the road turns greasy when it rains because the surface fines go slick before the water drains. Riders report that the two things that end Dempster trips are punctures and low-sides in the wet, in that order.
Repair kit. Carry what you would need to fix a flat yourself twice: plugs for tubeless, spare tubes and levers if you run tubes, a pump or CO2, and a way to check pressure. There is no garage between Dawson City and Inuvik. Fort McPherson and Eagle Plains are settlements, not service centres.
Protection. Handguards, a decent screen and something over the headlight are worth having. Stone chips from oncoming traffic are constant on a gravel highway, and the vehicles you meet are frequently trucks travelling at highway speed.
Season, crossings and practical detail
Season. The Dempster is an all-season road but not an all-season motorcycle route. The practical riding window is summer, roughly June to early September. The constraint that catches people out is not snow — it is the river crossings. The Peel and Mackenzie are crossed by the ferries MV Abraham Francis and MV Louis Cardinal from June to October, and by ice bridges from late November to April. During freeze-up in the autumn and break-up in the spring, neither is running and the road north of the Peel is cut. As of August 2026 those are the stated seasons; check the Northwest Territories ferry status and Yukon road report before you commit, because both dates move with the weather every year.
Weather. This is subarctic country crossing two mountain ranges. Snow in summer is possible, high wind is normal in the Richardsons, and a construction crew was nearly lost to a blizzard there in 1979. Rain is the more common problem: it turns the surface slick and it fills the ruts.
Daylight. Eagle Plains sits only 20 km south of the Arctic Circle and gets roughly ten minutes of civil twilight at the summer solstice, which is to say the sun barely sets. Long daylight is the one thing genuinely on your side up here.
Signal. Do not plan around mobile coverage. Between settlements there is effectively none, and a satellite messenger is the standard piece of equipment for this road rather than a luxury.
Beyond Inuvik. The Inuvik–Tuktoyaktuk Highway opened in November 2017, giving year-round road access from Inuvik to the Arctic Ocean and completing the first all-weather road route from the Canadian road network to the Arctic coast. If you have come this far, you will ride it.
Gear notes for a road with no signal and no garages
Everything on the Dempster comes back to self-sufficiency, and two pieces of it are worth planning properly. The first is tyre pressure. On a 736 km gravel run with 369 km between the first two fuel stops, a slow puncture that you notice at the next stop instead of when it starts is the difference between a plug and a recovery. Our tire pressure guide covers how loose surface and load change what you should be running, and a TPMS sensor puts a live number in front of you on a road where there is nobody to ask and nothing to check against.
The second is navigation and power. There is no coverage between settlements, so anything that fetches map tiles on demand is dead weight from the moment you turn off the Klondike Highway. Loading the whole corridor in advance for offline navigation on a handlebar display keeps your distances, ferry points and fuel stops in front of you, and riders on the JADO S6 get that on a screen that survives dust and rain rather than a phone taped to a bar. Power is the same problem: Eagle Plains is a hotel, not a hub, and a bi-directional 100 W charger that fills devices off the bike during the day and works as a power bank overnight means the satellite messenger and the phone never run flat at the wrong end of the road.

FAQ
Is the Dempster Highway paved?
No. It is gravel for effectively its whole length, built on a berm 1.2 to 2.4 m thick to keep road heat from melting the permafrost underneath. That design is the reason it will not be paved.
How far apart is fuel on the Dempster Highway?
The first fuel is at Eagle Plains, km 369, which is also the only place with fuel and lodging between Tombstone Territorial Park and Fort McPherson. Fort McPherson at km 550 is the second and last service point. Inuvik is at km 736. Plan for a 369 km opening leg, or closer to 409 km if you start from Dawson City.
What bike and tyres do you need?
An adventure or dual-sport bike with long-travel suspension and useful fuel range, on 50/50 or 80/20 tyres with a tough carcass. Street tyres are the wrong tool: the gravel includes sharp shale that cuts sidewalls, and the surface goes slick in rain. Carry plugs or tubes, a pump and a way to check pressure, because there is no garage on the road.
When can you ride it?
Summer, roughly June to early September. The limiting factor is the Peel and Mackenzie river crossings: ferries run June to October and ice bridges from late November to April, so during freeze-up and break-up the route north is cut entirely.
Is there mobile coverage?
Effectively none between settlements. A satellite messenger is standard equipment for this road rather than an extra.
