Introduction
Wisconsin is home to stunning caves formed over millions of years. These magical nature landmarks offer a mix of geology and adventure.
I still remember the first time I took my kids into a cave. The echo of dripping water, presence of little sunlight and the cool, mineral-scented air left them astonished.
As an outdoor enthusiast in Wisconsin who grew up exploring the mountains and wilds, I’m always chasing adventure and drawn to the beauty of nature.
Below, I’ll walk you through five of the best caves across the state. Whether you’re a curious traveler, a geology enthusiast, or just looking for a unique weekend family activity, you should consider exploring these unforgettable sights.
5 Top Caves in Wisconsin You Should Visit
Crystal Cave
With a 1-mile distance and over 70 feet underground, Crystal Cave is Wisconsin’s longest cave. The historic landmark is located near Eau Claire in Spring Valley.
The cave earned its name from the tiny, unique druzy crystal formations found underneath. You will also find stalactites and stalagmites when you explore the deep passages beneath.
The cave was formed from dissolving dolomite rock at the bottom of an ocean over 450 million years ago. Some bat species dwell in the darkness among columns and the path through sometimes requires a bit of ducking.
Crystal Cave takes about one hour to tour. Throughout the guided tour, you’ll learn about the cave’s history as you descend below ground.
Above ground, the cave is a fun destination for kids and adults with mini golf, hiking trails, picnic areas, and gem panning (digging).
Crystal Cave is open daily from May 27 to October 31, but hours may vary.

Eagle Cave
Eagle Cave is one of Wisconsin’s largest caves and was opened to the public in 1938.
It is located near Blue River, has over 3000 feet of passages, and formed through onyx, a translucent agate-related mineral formation.
As you explore underground, your tour guide will share historical information and interesting geological facts about the cave. And you can also spend a night in the caves. There’s a youth-group program started in the 1950s that allow visitors to do so freely.
Eagle Cave is open for guided summer tours on Thursdays through Sundays (from Memorial Day to Labor Day). Away from the cave, there are lots of other fun activities you can enjoy, including canoeing, mini golf, and camping.

Cave of the Mounds
Located in Blue Mound, Cave of the Mounds was discovered in 1939 after a routine quarry blast by workers in the area.
This national landmark features a 750-foot limestone cave that lies over 40 feet underground. Going through the cave, you’ll find a color palette of reddish brown, purple, gray, and black due to various (harmless) bacteria formations. With added lighting, you’ll also see other formations that resemble melting frosting, dangling fangs, and rippling coral.
Although the Cave of the Mounds is privately owned, there’s a public-private partnership with the National Park Service to manage and protect it for future generations. The cave earned a National Natural Landmark recognition in 1998.
Some walkways within the cave make navigating easier. Guided tours are available all year-round and self-paced tours can be done in an hour. The cave is open daily from 9 am to 5 pm.

Maribel Caves
Maribel Caves is located in the county park in Coopertown, just near Manitowoc, Wisconsin.
It was formed from a series of ever-changing caves and tunnels partially above ground discovered and excavated for the public.
All Cherney Maribel Caves have rustic outdoor entrances with narrow passageways and can only be crawled through the tight spaces (may not be for you if you are claustrophobic). They feature open spaces and are generally considered an accessible attraction with paved walkways and lights.
Most of the caves in the park, including Pancake Cave, Coopers Cave, Staircase Cave, and Tunnel Passages, are open for self-guided exploration during normal park hours. Others like the Spring Cave, Tartarus Cave System, and Sinkhole Cave are only open for special tours. You can read more about each of the caves and a little history on the website.
Visiting Cherney Maribel Caves County Park will be a thrill if you’re into outdoor adventures and hiking. It’s a great place to go if you want to spend a day in nature, tour the caves, and explore the surrounding park area.

Cave Point
Cave Point is on the shores of Lake Michigan in Door County, just about 8 miles northeast of Sevastopol.
Unlike other caves in Wisconsin, this cave was formed from pounding waves crashing against the limestone cliffs over thousands of years.
As you move through, you’ll experience the limestone ledges and see some of the formations from above. If available, light gives the water a blue color as the waves crashes against the limestone.
Since Cave Point is located in a premier family vacation spot, you get to enjoy breathtaking views of Lake Michigan and explore suitable fishing areas around the lake.
Cave Point attracts over 1 million visitors per year and is open all year round for free visits.
