About This Route
North Fork Road offers 26 miles of unpaved gravel from Polebridge Ranger Station to the Canadian border, ideal for fat-tire or gravel mountain bikes in Glacier National Park's remote northwest corner. Wind through cedar forests, past Bowman Lake's turquoise waters, with 1,500 feet elevation gain. Accessible year-round but best summer; remote feel amplifies solitude, perfect for intermediate riders seeking adventure beyond pavement.
Safety Considerations
High grizzly density demands bear spray on your person; NPS recommends groups of four and noise-making via bells or shouts at turns. Washboard gravel causes washouts; descend at controlled speeds under 15 mph. No cell service past Polebridge; inform rangers of itinerary. Wildlife like moose on roads at dawn/dusk; yield right-of-way. Adhere to Leave No Trace: camp only designated sites like Bowman Lake Campground. Hydrate aggressively; water scarce after Kintla Creek.
Essential Gear
Choose wide tires (29x2.6 Schwalbe Nobby Nic) for traction. Bear-proof food canister (Bare Boxer) mandatory. Navigation via Gaia GPS app with offline maps. Emergency bivy (SOL) for overnights.
