Chemin de la Réserve faunique de Port-Cartier–Sept-Îles — Côte-Nord Highland Interior Circuit
Precambrian shield deep cuts on the Côte-Nord.
The Réserve faunique de Port-Cartier–Sept-Îles covers nearly 6,400 square kilometres of granite ridges, lake chains, and black spruce bogs between Highway 138 and the Labrador border hills. The main access road off Route 138 near Port-Cartier is gravel all the way in, but the interior spurs degrade fast — loose rock ledge, exposed root crossings, and seasonal water bars that catch low-slung vehicles by surprise. The Rivière aux Rochers crossing at roughly kilometre 55 is the gnarliest choke point: a wide, rocky ford that reads about two feet in August but surges unpredictably after coastal rain systems blow in off the Gulf. Woodland caribou are a genuine presence here — you’ll see tracks on every sandy section if not the animals themselves.
Moderate overall, but specific spur roads push into Difficult territory. High-clearance 4WD minimum; a second vehicle or solid recovery gear is smart given the distance from help. The reserve requires a SÉPAQ access permit — purchase at the entry station or online through sépaq.com. Fuel at Port-Cartier or Sept-Îles before entry. Cell service is spotty on the first 20 km and nonexistent beyond. Best season is late June through early October; the reserve is closed to vehicle traffic during spring thaw. Fishing is exceptional if you carry a Quebec licence. Plan for at least two nights to make the distance worthwhile — designated campsites exist throughout the reserve interior.

Frequently asked questions
Can a stock 4Runner or Land Cruiser handle this trail without modifications?
A stock 4WD with genuine high clearance — think 8+ inches — will manage the majority of the 154 km circuit. The rocky Precambrian surface throws up sharp, angular chunks that punish low-slung all-wheel-drive crossovers, so leave the RAV4 at home. Aired-down all-terrain tires are strongly advised.
When does the reserve open for the season and is snow an issue in June?
SÉPAQ typically opens the reserve for vehicle access late June once snowmelt clears the highland roads — calling ahead to confirm is worth it because the 2,000+ ft interior holds snow longer than the coast. The window closes around late October when freeze-thaw cycles turn gravel to mush and early snowfall returns.
Do I need a permit to drive through the Réserve faunique de Port-Cartier–Sept-Îles?
Yes — access requires a SÉPAQ daily pass purchased through their website or at the reserve entrance. Fees cover vehicle access and camping where applicable; rates change seasonally so check sepaq.com/rf/pcs/ before you leave. Running the gate without a pass draws fines from reserve wardens who do patrol the interior.
What's the hardest section on the circuit and what makes it technical?
The highland plateau segments involve embedded rock shelves and water bars that drop abruptly with minimal runup room — slow, deliberate tire placement is more critical than horsepower. Water crossings on the interior drainages can run knee-deep through June and after heavy rain, with no bridging on several of them. The elevation change is gradual but the surface keeps you honest the whole way.
How far is the nearest fuel stop and is there any cell service if something goes wrong?
Port-Cartier is your last reliable fuel before entering — fill up completely, as 154 km of low-gear driving burns more than highway estimates suggest. Cell service is effectively dead once you climb past the coastal fringe, so a satellite communicator like a Garmin inReach is the only real safety net out here.
