Giant’s Ridge Iron Mine Historic Circuit
Iron Range mining ruins and technical rock
The Giant’s Ridge area near Biwabik sits atop some of the Mesabi Iron Range’s deepest excavations, where century-old open pit mines created a moonscape of red rock walls, flooded pits, and rusted machinery that’ll humble your 4×4. This technical loop drops into the old Biwabik Mine through a series of shelf roads carved into iron ore tailings, passing massive steam shovels abandoned in place when the ore ran out in 1979. The descent into Pit 7 requires careful line choice through loose rock and around washouts that’ll swallow a wheel if you’re not paying attention.
This is expert-level terrain demanding rock sliders, skid plates, and a spotter for the steepest sections. The iron ore tailings turn to slick clay when wet, making this a dry-weather-only proposition from June through September. No permits required, but respect private mining claims and stay on established routes. The old Biwabik Mine Office has trail maps and local knowledge. Water and fuel available in nearby Virginia or Hibbing. Camp at Bear Head Lake State Park or find primitive spots along the Embarrass River, but watch for unstable mine edges and deep water-filled pits.

Frequently asked questions
What kind of vehicle modifications do I need for Giant's Ridge Iron Mine Historic Circuit?
This expert trail requires significant armor including skid plates, rock sliders, and preferably 35+ inch tires with lockers. Stock vehicles will get destroyed on the rocky descents and technical sections.
Is Giant's Ridge accessible in winter or early spring?
No, stick to June through September only. Minnesota winters make this trail impassable, and spring thaw creates dangerous conditions on the steep rocky sections.
Do I need permits to run the Giant's Ridge mining circuit?
The trail crosses mixed private and state land, so check current access status before heading out. Some mining areas may have restricted access depending on ownership changes.
What's the hardest part of this trail?
The steep rocky descents into the old pit mines are brutal - expect body damage if you're not experienced with technical rock crawling. The mining equipment remnants also create tight navigation challenges.
How many water crossings should I expect on Giant's Ridge?
There are several water crossings that can vary significantly with rainfall and mining runoff. Bring recovery gear as some can be deeper than they appear, especially during wet seasons.
