SOME ADVICE BEFORE SETTING OFF ON YOUR ADVENTURE
Even if you don't plan to go camping, take along what you need to be self-sufficient and comfortable for an extended period in the event of a problem, including a sleeping bag, stove, candles, lighters, food bowl, first-aid kit, and insect repellent.
Don't set off without planning your trip and stay. Book your lodgings and tours in advance and let people know you'll be arriving. For Chisasibi and other Cree communities, be sure to contact tourism officials for advice and information.
Take along warm and weather-appropriate clothing. Travelling north doesn't necessarily mean it'll be cold, but as in any place else, the weather may surprise you. The difference here is that you won't come across shops to help you out.
Between Matagami and Radisson, there is no cellphone coverage. A public wi-fi network is accessible at the truck stop at Kilometre 381. To find your way around, use an application such as map.me, from which you can download maps beforehand. Thanks to these maps, you can locate your position with your phone's GPS signal, even without a data connection.
If the GPS suggests you take a forest road, disregard it and stay on the paved road. There is only one road, the Billy Diamond Highway, which you must stay on at all times.
Take along plenty of water and food so as to self-sufficient. There are grocery shops in Matagami, Radisson, and Chisasibi, but none in between, with the exception of a few basic goods at the Kilometre 381 truck stop.
Make sure your vehicle is in good condition and, if possible, carry a real spare tire, mounted on a proper rim, not just a spare wheel. The road is well-paved and offers a comfortable ride. It's as safe here as anywhere else in Québec. It's just that in this part of the country, you don't have the option of stopping at the garage in the next village.
Refuel wherever you can.
