mineWhile visiting the Copper Country we invite you to experience the best in underground mine tours: a tour through the historic Adventure Copper Mine. Experience the mine as the miners did over 160 years ago with a single light on your hard hat. There are no other lights underground - just like it was for them.

Want to go where no one has been in 100 years? The Captain's Tour, on the 2nd level, had been flooded since the mine closed in 1920 except for a brief two week period in the 1980's when prospectors were mining some of the stopes for copper specimens. Now open we have discovered that there are considerably more artifacts left in place including the rails from the tram system, timbers from loading chutes, shovels, powder boxes, a few tram cars, and even an old pump used for the original dewatering of the mine.

The Adventure Mine operated from 1850 to 1920 and is one of the best preserved mine sites of its age. Like almost all of the mining locations of the Copper Country, the Adventure was opened on existing prehistoric excavations located on Adventure Bluff. These prehistoric workings date to about 5,000 years before the present-day and were very extensive. Although the Adventure always showed great promise and millions of dollars were spent pursuing that dream, the mine always won out in the end. It never produced a profit.

Located in Ontonagon County at the base of the Keweenaw Peninsula in Michigan's Western Upper Peninsula, the Adventure Mining Company in Greenland, MI is only a 30 minute drive from Porcupine Mountains Wilderness State Park. We offer four guided underground tours of one of the best preserved copper mines in Michigan. Walk through part or all of the tunnels on the first level or try your hand at rappelling with a rope and harness to the second level of the mine...the choice is yours!
