Details below 👇🏻 Just 1h 40m from Milwaukee and about 2h 40m from Chicago, caveofthemounds completely blew us away. Discovered by accident in 1939, this underground cave is filled with stunning crystal formations that have been growing for over 1 million years — and seeing it in person is unreal. The self-guided tour takes about 45–50 minutes, and the paved, well-lit paths make it super easy for all ages (yes, even grandma approved 🥹). And don’t skip the gift shop — if you have kids, the gem panning experience at the end is a must. My boys were obsessed! Hours: Open year-round Spring hours are typically 9am–5pm (last tour around 4pm) Check their website before visiting for seasonal updates Save this for your next Wisconsin family adventure 📍✨ #midwestblogger #explorewisconsin #discoverwisconsin #midwesttravel #wisconsintravel cave of the mounds, explore Madison, family day trip in Wisconsin, hidden spots, amazing cave, Chicago travel
