Lakeland Park

If you live in Lake Geneva and have kids, you already know about this place — and if you don’t, someone’s going to tell you about it the first cold snap of the season. It’s a free indoor playground, which honestly feels like a small miracle when it’s February and everyone’s going stir-crazy. The main jungle gym is big enough to actually tire out older kids, but there’s a separate toddler zone so the little ones aren’t getting steamrolled. Someone clearly thought through the details too — the bathrooms have toddler seats and step stools, which parents of small kids will absolutely appreciate. Clean, safe, free, and actually fun for the whole range from babies to tweens.
