Minnesota's first iron ore mine—the Soudan Mine—opened in 1882. Operations went underground by 1892 since the ore body continued deep into the ground.

The mine's value was in the special kind of ore it produced. The ore's high oxygen content was used to make high-quality steel in open-hearth furnaces.

When technology changed, the ore from the mine was no longer needed. Low-cost ores of the Mesabi Range took over, and Soudan Mine closed in 1962.

Today, you can explore the last level that the miners worked.

Underground mine tour

Experience the life of the miner as you travel by cage 1/2 mile underground. Once underground, you'll ride the rails 3/4 mile to the last and deepest area that was mined. You'll learn firsthand why this mine was called the "Cadillac of Mines," and gain insight into the working conditions of the miners and their remarkable mining methods.

  • 1.5 hours for the tour.
  • Close space for the three-minute ride down into the mine and two narrow spiral staircases.
  • Tours run daily from 10 a.m. to 4 p.m., Memorial Day weekend through the end of September.

Reserve online or by calling 866-857-2757.

Secrets of the deep: science tour

This science tour starts with a cage ride to the 27th level of the mine where visitors enter the former physics lab to learn about the major experiments that were conducted there. Participants will also learn how scientists are using bacteria found in the mine in the search for a treatment for white nose syndrome (a fungal disease affecting bats), an alternative energy source or a means of purifying water. 

  • This tour will be offered again in 2022.
  • 80 minutes for the tour.
  • Close space for the three-minute ride down into the mine.
  • The mine is 51 F year-around, remember to bring a warm jacket and sturdy shoes.

Reserve online or by calling 866-857-2757.

Walking drift tour

The tour explores how geologists found the iron ore buried deep in the Earth’s crust. Visitors don hard hats and enter a "cage" for the half mile descent into the mine. Once underground visitors search for geologic clues on a ¾ mile walk that follows the route miners took to work each day. They will also discover the tools that the mine used in their exploration for the iron ore. At the end of the tour, visitors will ride a train back to the beginning of their journey. It will involve walking on uneven surfaces in a cold, dark and wet environment. The tour is available for individuals 10 years of age and older.

  • This tour will be offered again in 2022.
  • 2 hours for the tour.
  • Close space for the three-minute ride down into the mine and two narrow spiral staircases.
  • The mine is 51 F year-around, remember to bring a warm jacket and sturdy shoes.

Reserve online or by calling 866-857-2757.

About the bats

Soudan Mine is home to one of Minnesota's largest bat hibernacula. It is estimated that between 10,000 and 15,000 bats use the mine for their winter home. The bats can be found throughout the mine in the winter. In late June and July they leave the mine to roost in the woods, where—like most bats in Minnesota—the females will have one pup. The bats return to the mine in late July and early August, when you can often see them at dusk as they leave the mine in search of food.

White-nose syndrome (WNS)—a disease caused by a fungus dangerous to bats—has been confirmed at the park. WNS is harmful and mostly fatal to hibernating bats, and has decimated bat populations in the eastern portions of the United States and Canada. It is transmitted primarily from bat to bat and is not known to pose a threat to humans, pets, livestock or other wildlife.

Public tours of the mine are continuing. To help keep the fungus from spreading, visitors are required to walk across special mats designed to remove spores from footwear. Visitors also are advised not to visit other caves or mines with any clothing, footwear or gear they have used in areas where WNS or the associated fungus is present, because washing alone cannot sufficiently disinfect clothing.

Learn more about white-nose syndrome and what you can do to help slow its spread.
