This is a great day trip away from the resort. Located in Upper Michigan near Lake Superior are some awesome Mining caves.
They offer a variety of tours of the cave from easy that you can do with kids to advanced where you can repel in the mine.
Here is some info from them:
Our tours are as authentic as you’ll ever find. No fancy lights or modern marvels here, just real mining the way it really was! All guests are furnished with a hard hat and headlamp. There are no other lights underground, period. Trails underground are sometimes rough so wear appropriate footwear. The temperature in the mine is 48 degrees regardless of outside air temperature. A light jacket is recommended. Cameras are always welcome! Tour specific details are listed below.
There are no set times for tours to start, we offer tours on a first come, first serve basis. Generally we can get you tour started within 15 minutes of your arrival. If you are bringing a large group, we appreciate a heads up so we can plan ahead for you. We also ask that Miner’s Tours start before 3:00pm (eastern time)
