The Ice Age missed one spot in Iowa — now it’s the state’s most underrated destination

Where three states meet on limestone

You expect Iowa to be flat. Cornfields from horizon to horizon, right?

Dubuque throws that out the window. This city sits right where Iowa, Illinois and Wisconsin come together on the Mississippi River, and the land here looks nothing like the rest of the state.

Steep limestone bluffs rise over deep river valleys because the ancient glaciers skipped this region entirely. They call it the Driftless Area, and it gave Dubuque a landscape most people never connect with Iowa.

The city goes back to 1785, making it the oldest in the state, and the story of how it got here starts with fur, lead and a deal between cultures.

A fur trader and a lead fortune

A French-Canadian fur trader named Julien Dubuque showed up in 1785 and built a close relationship with the Meskwaki people, who knew where the lead deposits sat.

They shared that knowledge, and Dubuque got rights to mine the land. He called the area the Mines of Spain and ran those mines until he died in 1810.

After the Black Hawk Purchase Treaty opened the land in 1833, Irish and German immigrants poured in for the mining jobs and cheap land. The city earned the name Key City, a gateway pushing west.

The elevator a banker built for lunch

The Fenelon Place Elevator climbs 189 feet up a limestone bluff at a 41-degree angle. People call it the shortest, steepest scenic railway in the world, and the reason it exists is almost too good.

A former mayor and banker named J.K. Graves built it in 1882 because he kept burning his entire lunch break driving his horse and buggy around the bluff to get home. A fire destroyed the original in 1893, but ten neighbors formed a company and rebuilt it.

That rebuilt version still runs from April through November, and from the observation decks at the top, you can see into all three states.

200 species on a 14-acre riverfront campus

The National Mississippi River Museum and Aquarium sits right on the riverfront in the Port of Dubuque, and it carries a Smithsonian affiliation.

The campus stretches 14 acres and holds more than 200 species, including giant catfish, sturgeon, river otters, a bald eagle, stingrays and an American alligator.

You can climb aboard the William M. Black, a National Landmark steam dredge boat, or try piloting a river barge through interactive exhibits. A 4D theater, daily animal encounters and hands-on science activities keep it interesting no matter your age.

16 miles of trail through land that started it all

The Mines of Spain sits just south of the city, covering 1,439 acres of National Historic Landmark ground with more than 16 miles of hiking trails.

You walk through wooded bluffs, restored prairies and wetlands, and some trails follow the Mississippi River shoreline.

The Julien Dubuque Monument stands on a bluff above Catfish Creek, a stone tower built in 1897 to mark the burial site of the city’s founder.

Iowa designated this a Watchable Wildlife Area, so keep your eyes open for bald eagles, bobcats, flying squirrels and wild turkeys.

Tiffany glass that started at a worlds fair

St. Luke’s United Methodist Church on Main Street holds more than 100 stained glass windows by Louis Comfort Tiffany, the fifth-largest collection of his work in the country.

Church members first saw Tiffany’s glass at the 1893 World’s Columbian Exposition in Chicago and bought their first windows on the spot.

The centerpiece is the Good Shepherd window, which Tiffany created for that same exposition and reportedly called his finest work in glass. You can walk through for free on self-guided or docent-led tours.

A park born from an insult

Eagle Point Park covers 164 acres on a bluff above the Mississippi River and Lock and Dam No. 11. The park exists because of a challenge.

In 1907, a visiting park specialist said he had never seen a place where God had done more and people had done less. A local judge took that personally and led the push to build a great park.

In the 1930’s, a WPA grant funded the stone shelters, fish ponds and rock walls, which the American Institute of Architects later recognized as some of Iowa’s most important structures from that decade.

You can stand at the blufftop and watch massive river barges work through the lock and dam far below.

A lead miners cave full of crystal

James Rice discovered Crystal Lake Cave in 1868 while mining for lead.

The cave holds crystal formations including stalactites, stalagmites and rare helictites, and guided tours take you through about 3,000 feet of well-lit passageways.

The temperature stays cool and steady year-round, so it feels the same in July as it does in January. The cave’s namesake crystal lake is a narrow pool, and you see it through a window cut into the cave wall.

The cave has welcomed the public as a show cave since 1932.

Old warehouses turned into an arts district

The Millwork District once hummed with lumber mills and warehouses along the riverfront, then sat empty for years.

The city turned those old brick buildings into an arts and culture hub, and today you find local shops, restaurants and creative spaces with much of the original architecture still intact.

The Dubuque Museum of Art, Iowa’s oldest cultural institution, recently moved to a temporary space in the district while a new campus goes up.

Night markets, live music and seasonal festivals fill the streets throughout the year.

Murals on every other block downtown

In 2015, a local nonprofit called Voices Productions started a public art campaign that has covered downtown Dubuque in dozens of large-scale murals.

Artists from across the country have painted bold portraits, abstract works and everything in between on the old brick walls.

You can take a self-guided walking tour to find murals tucked into alleys, side streets and building facades.

The whole project turned the downtown streets into a free outdoor gallery, and you keep finding new ones around corners you thought you already checked.

56 free acres kept alive by 350 volunteers

The Dubuque Arboretum and Botanical Gardens covers 56 acres, and every bit of it is free to visit year-round from dawn to dusk.

More than 60 types of gardens grow here, including a Japanese garden, a rose garden, herb gardens and a children’s garden.

The whole operation runs on the work of about 350 volunteers who create and maintain every section.

About 55,000 people come through each year, and on a quiet morning, you can walk the grounds for an hour without running into a crowd.

The riverwalk that ties it all together

The Riverwalk runs along the Port of Dubuque and connects the river museum, the Grand River Center and other waterfront spots in one stretch.

The city built it as part of a larger project that turned 90 acres of old industrial land into a campus built around the Mississippi.

Benches, public art and views of passing river barges line the path, and you can cover most of the waterfront attractions on foot.

It is a good way to end a day in Dubuque, with the river right beside you and the bluffs rising behind the city.

Explore Dubuque, Iowa

You can find Dubuque in northeast Iowa on the Mississippi River, about 190 miles west of Chicago and 330 miles southeast of Minneapolis.

The Fenelon Place Elevator, National Mississippi River Museum, Mines of Spain and Eagle Point Park all sit within a short drive of downtown.

The Dubuque Regional Airport ended its daily commercial flights to Chicago O’Hare in January 2026, so your best bet is to drive or fly into a nearby hub.
