Lake Vermilion–Soudan Underground Mine State Park
A historic iron mine, underground tour, headframes, bats, Lake Vermilion forest, and modern campground join industrial history with northern geology and recreation.

Artwork inspired by Clement Haupers
Soudan was Minnesota’s first iron mine and reached nearly half a mile underground. Guided tours descend in a cage and travel through cool, wet workings where geology, labor, ventilation, explosives, and ore transport become physical realities rather than diagrams.
The park now also includes Lake Vermilion shoreline and campground facilities, so visitors must choose between an industrial-history visit and a broader outdoor stay. Mine tours are seasonal, capacity-limited, cold, and physically constrained; reserve ahead and bring a layer even on hot days.

Quick guide
- Essential booking
- Reserve the underground mine tour before driving
- Bring
- Wear closed shoes and carry a warm layer
Move from surface machinery to underground working conditions
- Start with
- Treat the mine cage descent as working infrastructure and notice how quickly light, sound, and temperature change.
- Look closely at
- Use the headframe to trace how people, ore, equipment, and signals moved between surface and shaft.
- Connect the story
- Return outside to Lake Vermilion forest so the industrial site remains connected to its northern landscape.
- Plan around
- Reserve the underground tour and prepare for cold, confinement, hard hats, and uneven historic surfaces.
Good to know
The underground tour involves a mine cage, darkness, moisture, noise, and confined transport; the surface park remains worthwhile for visitors who skip it.
