Liard Highway — Fort Nelson to Watson Lake via the Muskwa River and Coal River Hot Springs
Canada's loneliest wilderness highway.
The Liard Highway (BC-77 / NWT-7) runs north from Fort Nelson, British Columbia through the foothills of the Muskwa-Kechika Wilderness before crossing into the Yukon at Watson Lake. The road was only completed in 1984 and still earns its reputation as one of the most isolated paved-and-gravel corridors in North America. The real draw is Coal River Hot Springs — a free, roadside thermal pool at kilometre 170 that you’ll likely share with nobody but a raven. Watch for stone sheep on the shale slopes near the Toad River section, bison wandering the gravel just north of the BC-Yukon border, and the Liard River bridge crossing at the hamlet of Lower Post, where the current can look like moving glass.
The road is mostly gravel with long paved sections; a stock 4WD with good all-terrain tires and two full-size spares handles it fine. The real killer is rock chips — drive with your lights on and slow down for oncoming traffic. Fuel up hard in Fort Nelson and again at Fireside if it’s open (don’t count on it). Best season is June through September; before that, spring breakup turns low sections to soup. Cell service is essentially zero for the full run. Carry a satellite communicator, extra fuel, and enough food for three days minimum. What you get out of it is honest wilderness — no Instagram crowds, no entrance fees, just moose and mountains.

Frequently asked questions
Can a stock Tacoma or 4Runner handle the Liard Highway without modifications?
A stock high-clearance truck with AT tires can manage it in dry summer conditions, but 4WD is strongly recommended. The gravel surface gets rough and washboarded, and soft shoulders after rain can swallow a tire — don't run it on street rubber.
When does the Liard Highway typically open and close for the season?
June through September is the reliable window. Spring breakup (April–May) turns the surface into a mud disaster, and early snowfall can hit by October. Check BC Hwy 77 and Yukon road condition reports the day before you leave — conditions change fast up here.
Do you need any permits or fees to drive the Liard Highway?
No permits required to drive the route itself. Coal River Hot Springs is a free, undeveloped hot spring on Crown land — no fees, no reservations. Dispersed camping along the corridor is also free.
What's the hardest section and what should I actually expect?
There's no single technical obstacle, but the difficulty is cumulative — 496 kilometres of gravel with no services, potential for deep mud after rain, and wildlife crossings that appear out of nowhere. The Coal River bridge area and any post-rain stretch near the Muskwa demand your full attention; the road can deteriorate significantly between condition reports.
How far apart are fuel stops, and is there any cell service along the route?
Fuel is available at Fort Nelson at the start and Watson Lake at the end — that's roughly 496 kilometres with nothing reliable in between. Carry extra fuel. Cell service is nonexistent the entire route; a satellite communicator (inReach or SPOT) is not optional on a highway this remote.
