At Delaware Mine Tours in Michigan’s Upper Peninsula, visitors can descend 100 feet underground and explore a real nineteenth-century copper mine without following a tour guide. The tunnels date to a mining operation that ran from 1847 to 1887, and you can walk through them at your own pace.

The experience starts with a short introductory video before visitors head underground. Inside, exposed copper veins, mining equipment, and educational displays reveal what working in the mine was like more than a century ago.

There’s more to explore above ground, including historic building ruins, old machinery, and walking trails. The property also preserves evidence of Indigenous copper mining dating back thousands of years, adding another chapter to the site’s history.

Copper made the Keweenaw Peninsula famous, and Delaware Mine Tours lets you stand right inside that story. The site sits at 7804 Delaware Mine Rd in Mohawk, Michigan, near the top of the Upper Peninsula.

It’s a historic mine turned into a museum you can walk through. The tunnels are real, the rock walls are real, and so are the leftover buildings scattered across the grounds.

What catches my attention is how hands-on the whole thing feels. You aren’t watching history from behind glass here.

You’re walking where miners once worked, breathing the same cool underground air.

The Upper Peninsula has only a few copper mine tours open to the public. Delaware stands out because it is family-owned and keeps its focus on learning rather than flash.

Getting there means heading north into the Keweenaw, where forests close in around the road. The drive itself sets the mood before you ever see a mine shaft.

Once you arrive, a visit unfolds in a clear order. It starts not underground, but with a short introduction that helps everything else make sense.

Start With a Video and a Friendly Talk

Before anyone heads down the stairs, there’s a little homework, and it’s the fun kind. Visitors watch a short informational video that covers safety and suggests things to look for on the tour.

The video also features the founder of the tours in their modern form. It’s a nice touch, because you hear about the mine from someone who cared deeply about sharing it.

Staff members often add a quick talk of their own. An archaeologist works on the property, and he shares what he and the team are uncovering about the site.

I’d pay close attention during this part. The tunnels make far more sense once you know what the miners were doing and why.

Think of it as a map for your brain. You’ll recognize features underground that you might otherwise walk right past.

Questions are welcome too. The people here clearly enjoy talking about copper, mining tools, and the history of the Keweenaw.

With the basics covered, you’re ready for the main event. The next step takes you straight down, one stair at a time.

Ninety-Eight Steps Into the Earth

Ninety-Eight Steps Into the Earth

Count them if you like. There are about 98 steps leading down roughly 100 feet into the mine.

The stairs aren’t steep, but there are plenty of them. Going down feels easy enough, while coming back up becomes a small workout for your legs.

Kids sometimes call them the scary stairs at first. Most get over that quickly once they reach the bottom and realize the adventure is just starting.

My advice is simple. Wear sturdy shoes with good grip, and take your time on the climb back out.

Families with little ones should plan for short breaks. Nobody is rushing you, so pausing to catch your breath is perfectly fine.

As you go deeper, you’ll notice the air changing. It gets cooler with each level, and the surface world fades behind you.

Reaching the bottom is a cool moment, both literally and in spirit. You’re standing inside rock that miners once worked by hand and machine.

From here, the tunnel stretches ahead into the dim light. That’s where the self-guided part of the visit truly begins.

Your Pace, Your Tunnel

Freedom is the big draw underground. Delaware Mine Tours is self-guided, so you set the speed instead of following a tour group.

The trail runs about 1,400 feet into the mine, going out and then back the same way. That gives you plenty of room to stop, look, and wonder.

Some people move through quickly. Others linger at every wall and kiosk, reading each detail along the way.

Many families spend around 45 minutes underground. Your time may differ depending on how curious everyone feels.

I can understand why the owners consider this flexibility special. Kids with short attention spans can move along, while history fans can slow way down.

The lighting is kept dim on purpose to reflect mining days. A small flashlight can help you spot details hiding in the corners.

Educational kiosks underground add helpful facts as you go. They explain what you’re seeing without a guide reciting a script.

All that wandering comes with one catch, though. The deeper tunnels stay chilly no matter what the weather is doing outside.

Pack a Jacket, Even in July

Summer sunshine stops at the top of the stairs. Down in the mine, it stays cold all year, and visitors are often surprised by the chill.

A sweater or light jacket makes a huge difference. Even on a warm Keweenaw afternoon, you’ll be glad you brought one.

Kids especially feel the cold quickly. Toss an extra sweatshirt in the car so nobody has to cut the tour short.

Shoes matter too. Mine floors can be uneven, and closed-toe footwear keeps your steps steady.

Rainy days actually work well for a mine visit. Underground, the weather above barely matters at all.

The owners have shown real kindness on soggy days too. One motorcyclist was invited to dry his riding gear near their fireplace.

Here’s a quick packing list in sentence form. Bring layers, a small flashlight, good shoes, and some patience for the stairs.

Don’t forget cash as well, since many visitors note the site is cash only. That’s an easy thing to miss when you’re used to tapping a card everywhere.

Once you’re dressed for the cold, the history underground gets much easier to enjoy.

Copper Mining Thousands of Years Old

Long before steam engines and mining companies, people were already digging copper here. Native peoples mined copper on the Keweenaw thousands of years ago.

Delaware Mine Tours shares more about this early mining than many visitors expect. Information on site discusses Native mining reaching back as far as 10,000 years.

That fact stopped me in my tracks. The copper story here didn’t start in the 1800s at all.

The Keweenaw holds unusually pure native copper. Early miners could work it using stone tools and fire.

Later, the copper boom brought large operations and workers from far away. Mines like Delaware helped shape towns, jobs, and culture across the Upper Peninsula.

Walking the tunnels with both chapters in mind feels different. You’re seeing one stretch of a very long timeline.

The archaeologist on site keeps adding new pieces to that timeline. Ongoing work called the Delaware Digs explores what the ground still holds.

History here isn’t finished being written. That ongoing discovery spills right out of the mine and onto the surface grounds.

Climb back into daylight and the exploring keeps going. The surface grounds hold old stone ruins and mining machinery along walking trails.

These pieces show how the mine worked from the top side. Buildings once supported the people and equipment deep below.

Many visitors spend another 15 to 20 minutes outside. Some stay much longer, wandering the paths and soaking in the view.

Signs on the surface have been limited in the past. The owners say they’re working on a web-based walking tour and adding QR codes to original buildings.

I like that plan a lot. Scanning a code beside a crumbling wall could turn a mystery into a story.

The Delaware Digs sites already use QR codes. Those spots highlight ongoing archaeological work on the property.

Trails also offer shaded places to sit and rest. It’s a pleasant break after all those stairs.

Bring your camera for the old machinery. Rust, stone, and green forest make for interesting photos against the Keweenaw sky.

And with all that shade, the grounds lend themselves to a slower, snack-friendly afternoon.

Junior Miners and the Skunk Signs Hunt

Kids get their own mission at this mine. A Junior Miner worksheet and a skunk signs activity turn the visit into a hunt.

Why skunks? The mine has a pet skunk connection that many visitors mention, and the theme has become part of the fun.

Children who finish the skunk signs activity can earn a patch. It’s a small reward that makes young explorers feel proud.

I’d grab the worksheet right at the start. It gives kids a reason to look closely instead of racing ahead.

The self-guided format helps families too. You can stop for breaks in several spots without holding up a group.

Leashed dogs are welcome on the self-guided tour as well. That’s handy for travelers who bring the whole household along.

Parents with pre-teens often find the visit holds attention well. The mix of stairs, tunnels, and outdoor trails keeps things moving.

Little ones may need extra help on the climb back up. Plan for some hand-holding and a snack waiting at the top.

Once the patch is earned, there’s usually one more stop kids ask about.

A Family Story Behind the Gift Shop

Every mine has owners, but this one has a heartfelt reason for its current ones. Laurie, the owner, is preserving her dad’s legacy at the site.

Her father, Tom, envisioned an affordable, educational experience. He wanted to share his knowledge and passion for Keweenaw history with everyone who stopped by.

That second-generation care shows in the details. New underground kiosks and a refreshed gift shop are among the recent additions.

The gift shop carries a wide variety of items. Laurie works to stock things at many price points.

She remembers how much joy a souvenir brought her as a kid. That memory guides what ends up on the shelves.

I find that detail sweet and very human. It turns shopping into part of the family story.

Staff and owners often chat with visitors after the tour. Many people leave knowing far more than they expected.

Buying something here supports a small, family-run business. That money helps keep the tunnels open for the next curious visitor.

Timing matters, though, because the mine doesn’t welcome guests year-round.

Plan Around Keweenaw Snow

Snow rules the Keweenaw, and it decides when the mine can open. Delaware Mine Tours closes for winter because heavy snowfall makes the area hard to reach.

Road signs even note that the route isn’t plowed in winter. In past seasons, the owners closed around mid-October.

Checking current dates before you go is a smart move. Seasons can shift a little from year to year.

Late spring through early fall is your window. Autumn colors make the northern drive especially pretty.

Remember to bring cash for admission and gift shop purchases. Many visitors point out it’s a cash-only stop.

Restrooms are on site, which families always appreciate. You might also pack a cooler, since shaded spots outside work nicely for lunch.

Plenty of visitors spend about two hours total. Some wish they’d planned even more time to wander and chat.

Pair the mine with other Keweenaw sights for a full day. Lighthouses, shoreline views, and small towns all sit within reach.

Whatever else you plan, save energy for those 98 steps back to daylight.
