Boundary Waters Forest Road 116 Gunflint Access
Deep wilderness access to Canada border country
Forest Road 116 cuts deep into the Boundary Waters backcountry, following an old logging route that pre-dates the wilderness designation. This rough two-track winds through dense boreal forest and across multiple unnamed creek crossings before connecting to the historic Gunflint Trail near Magnetic Lake. The route passes several abandoned logging camps and offers access to some of the most remote sections of Superior National Forest, including views of the Canadian border lakes from elevated granite outcrops.
Expect difficult terrain with deep ruts, creek fords up to 18 inches, and fallen timber that may require chainsaw work. High-clearance 4WD with good approach angles essential, plus recovery gear for the mud holes. Summer months only – road typically impassable until June due to frost heaves and spring runoff. No services for 50+ miles, so carry extra fuel and water. Remote dispersed camping available, but you’ll need BWCA permits for some areas. This is genuine wilderness access for serious backcountry explorers.

Frequently asked questions
Can a stock Jeep Wrangler handle the water crossings on Forest Road 116?
Yes, but barely - the creek crossings can reach 18-24 inches deep depending on recent rainfall. Rock sliders and a snorkel aren't required but muddy bottoms can grab stock tires hard.
Is Forest Road 116 passable in early June or late September?
Early June is risky due to snowmelt runoff making crossings dangerous, while late September usually works until first hard freeze. Peak season is July-August for safest conditions.
Do I need a permit to drive Forest Road 116 or just camp?
You need a Motor Vehicle Use Map (MVUM) permit for the road itself, plus separate permits for any Boundary Waters entry if you cross into BWCAW. Dispersed camping along the route requires no additional permits.
What's the gnarliest section I should prepare for?
Mile 16-18 has three consecutive creek crossings with loose rock approaches and muddy exits. The second crossing has a nasty off-camber exit that's claimed more than a few differentials.
How much fuel range do I need for this trail?
Plan for 60+ miles round trip from Grand Marais with no services - carry extra fuel if your rig gets under 12 MPG. The rocky terrain and water crossings will kill your fuel economy.
