Explorium Information

Take some time to read about Mr. Lois “Curly” Radke, a local citizen who was instrumental in the Horicon Marsh becoming the place that it is today.

With the ongoing concerns over COVID-19, the Horicon Marsh Explorium will remain closed until further notice. Please stay safe and healthy with your families. We look forward to seeing you again when the time is right.

Visitors have a unique opportunity to travel through time as they explore some of the exciting new features on display at the Horicon Marsh Education and Visitor Center in Horicon, WI. Long before Horicon Marsh achieved international status as an important bird and wildlife area and a destination for outdoor recreation, glaciers carved a basin where a wetland would one day form. Today, guests of Horicon Marsh’s Explorium can get a glimpse of life at Horicon Marsh thousands of years before European settlement and witness how the current wetland came to be. The experience is narrated by a Clovis spearpoint that keeps visitors company throughout the journey as they view, listen to, touch, and even smell exhibits that document the changes to the marsh over time.Videos and interactive displays greet guests at every turn, encouraging audiences of any age to learn more about the history and ecology of Horicon Marsh. A woolly mammoth replica that children are free to touch and climb represents wildlife that roamed the land during the Ice Age and also served as an important food source for early Native Americans. Relics from the age of European settlement as well as modern hunting and trapping equipment illustrate the marsh’s popularity as a waterfowl hunting site. Games encourage visitors to learn about wildlife identification. Viewers can also gain a singularly thrilling perspective on the management and conservation activities currently occurring on the marsh before heading out to enjoy it for themselves. These exhibits are just a taste of the many educational themes in the new Explorium.
