7 Awe-Inspiring Natural Wonders of Wisconsin

From stunning sea caves to towering waterfalls, Wisconsin is home to breathtaking natural wonders you’d never expect. Created by Mother Nature and ripe for exploring, these scenic spots are the backdrop to lasting memories, including some of the best hiking, biking and kayaking you’ll find in the Midwest.

So, gather your crew and head out on a refreshing escape to these unexpected Wisconsin wonders.

1. The Apostle Islands National Lakeshore

Calling to the explorer in all of us, the Apostle Islands National Lakeshore is an archipelago of 21 islands dotting the waters of Lake Superior. Featuring some of the most pristine remaining sandscapes in the Great Lakes region, the Apostle Islands have been named by National Geographic magazine as a top place to visit.

Among the windswept beaches and cliffs, spectacular sea caves have been carved out over thousands of years by the rhythmic waves. In summer, kayak straight into the caves to marvel at them up close.

While beautiful from the shore, when the weather is warm, you must see the islands by boat or, even better, set foot on an island and camp at one of the 60-some rustic sites. Take a grand tour on Apostle Island Cruises and you’ll see one of the best historic collections of lighthouses anywhere in the country. This area is also home to many famous shipwrecks, making it a popular spot for scuba divers, too.

Find the right tour guide for you and your crew to show you around these legendary islands.

2. Big Manitou Falls

In Pattison State Park, discover the 165-foot-tall Big Manitou Falls, the fourth-tallest waterfall east of the Rocky Mountains. The best vantage point to see Big Manitou is from the south, where two overlooks provide head-on views of the waterfall. You can get much closer to Little Manitou Falls, a nearby 31-foot drop. Both falls have wheelchair-accessible paved paths for easy access.

With more than nine miles of hiking trails to explore and a mix of campsites in the park, you and your crew can enjoy a quick visit or a multi-day adventure to this Wisconsin wonder.

3. Cave of the Mounds

Cave of the Mounds is a designated National Natural Landmark, but it may be easier to remember it as the “jewel box” of America’s major caves, so named for the delicacy of its formations.

The main cave began forming more than a million years ago, and every drop of water entering the cave leaves calcite crystals on the ceiling, walls and floor. It can take upwards of 150 years to deposit one cubic inch of these crystal formations!

The cave was accidentally discovered in 1939 when workers removing limestone from a quarry blasted into rock, revealing this stupendous underground cavern with rooms, galleries, nooks and crannies.

Whichever season you visit, the cave will be the same temperature: a cool 50 degrees. General Manager Joe Klimczak has noted more passageways are still being discovered: “The cave is still unveiling itself to us, and we’re just a blip on the geologic timeline.”

4. Devil’s Lake State Park

Devil’s Lake State Park, not far from Wisconsin Dells, is the largest and most visited state park in Wisconsin. Each year, hundreds of thousands of visitors enjoy the 360-acre spring-fed lake, the 500-foot bluffs teetering over it and the 30 miles of trails that comprise the trifecta of this natural wonder.

Scientists believe the bluffs were formed 1.6 billion years ago, making them one of the most ancient rock outcrops in North America. The ranges are known for their plum-colored quartzite–a strong, dependable rock perfect for experienced rock climbers. Make a point to hike the east bluff to see Balanced Rock and Devil’s Doorway, two one-of-a-kind formations created by Mother Nature.

5. Eagle River Chain of Lakes

If one Wisconsin lake is wonderful, then how would you describe 28 lakes, all interconnected? Deep in the Northwoods of Wisconsin, the Eagle River Chain of Lakes is the largest inland chain of lakes in the world. The depth of these lakes varies widely from one to the next, providing sufficient space for whatever floats your boat, be it water skiing, wakeboarding, pontoon cruising, canoeing, kayaking or fishing.

Here’s a little secret about this Chain of Lakes: While the lakes themselves are 100 percent natural, it was the work of humans that connected them. Dams were built to hold up the Wisconsin and Eagle Rivers as a way to connect the lakes to serve the logging industry and generate electricity. Today, there are abundant boat landings along the shore for anglers hoping to catch bluegill, perch, northern and the goliath of freshwater fish, the musky.

6. High Cliff State Park and the Niagara Escarpment

The locals call it “The Ledge” – the limestone cliff that runs through High Cliff State Park, situated on the eastern shore of Lake Winnebago, Wisconsin’s largest inland lake.

Mind you, this is no ordinary limestone cliff. It’s the Niagara Escarpment, a 440-million-year-old cliff that begins in Wisconsin and extends 1,000 miles to Niagara Falls. In fact, without the Escarpment, there would be no Niagara Falls.

In Wisconsin, this major land feature is rich with fossils, rare plant species, caves and waterfalls. This rock corridor also has Native American petroglyphs, pictographs and effigy mounds.

As you drive into the lower part of High Cliff State Park, you’ll have a clear view of the entire cliff. There are nine miles of hiking trails in the upper park, along with another nine for horseback riding. There’s also more than a mile of shoreline along the lake with a sandy beach, marina and public launch.

No trip to High Cliff is complete without scaling the Lookout Tower in the upper park, where you can see 30 miles to the north, west and south.

7. Horicon Marsh

Horicon Marsh is the largest freshwater cattail marsh in the nation. It’s located in southeast Wisconsin and is best known as a migratory stop for vast flocks of Canada geese. But you’re sure to find more than just geese on your visit to this hidden gem.

Upwards of 300 species of birds have been spotted here, including the largest nesting population of redhead ducks east of the Mississippi. It is here that you’ll also find the largest nesting rookery in Wisconsin for the great blue heron.

Essential for your visit to Horicon Marsh is a pair of binoculars to bring the wildlife closer to you without disturbing them. And be sure to get out on the marsh by boat, canoe or kayak!
