Superior National Forest Forest Road 177 Brule River Technical Circuit
Brule River granite technical challenge
Forest Road 177 penetrates deep into the Brule River watershed, following ancient trappers’ routes through some of Minnesota’s wildest country. The trail threads between massive granite boulders left by glaciers, crosses multiple tributaries of the Brule River, and climbs toward the Sawtooth Mountains through old-growth forest. The notorious Devil’s Kettle area requires technical navigation around exposed bedrock and seasonal waterfalls that have carved deep gorges through the Canadian Shield geology.
This is expert-level terrain demanding rock sliders, differential locks, and experienced spotters for the granite ledges and creek crossings. Late summer offers the best conditions when water levels drop, but even then expect challenging wet rock and loose gravel on steep grades. No permits required but inform someone of your plans – this is genuine wilderness with zero cell coverage. The reward is access to some of the North Shore’s most pristine camping and the chance to fish waters few anglers ever see.

Frequently asked questions
Can a stock pickup truck handle this trail?
No, this is an expert-level technical route requiring modified 4WD with skid plates, rock sliders, and aggressive tires. Stock vehicles will get damaged on the granite obstacles and creek crossings.
Is Forest Road 177 accessible in spring or late fall?
Best access is June through September when creek levels are manageable and snow has cleared. Spring runoff makes water crossings dangerous, and early snow can trap vehicles on remote sections.
Do I need permits to camp along the Brule River circuit?
No permits required for dispersed camping in Superior National Forest, but follow Leave No Trace principles. Campfires may be restricted during high fire danger periods.
What's the most technical section of this trail?
The granite ledge climbs near the Brule River headwaters require precise line selection and aggressive approach angles. Multiple vehicles have body damage from underestimating the rock steps.
How many water crossings should I expect on this route?
Plan for 6-8 creek crossings depending on seasonal flow, with depths typically 12-18 inches. Scout all crossings on foot first as granite bottoms can hide deep holes or loose rocks.
