What to do with Grandkids in Jefferson County WI

A full day of fun, fresh air, and family bonding — no screen time required.

Spending the day with your grandkids is all about making memories — and Lake Mills, Wisconsin makes it easy with its walkable charm, beautiful lakefront, and a variety of kid-friendly activities that don’t require hours of planning (or breaking the bank). Whether they’re toddlers with boundless energy, curious elementary-aged explorers, or laid-back teens, here’s a full itinerary to enjoy your time together — with stops tailored for all ages.

☀️ Morning: Lakeside Play & Nature Fun (Ages 2–8)

Start your day at Sandy Beach Park, located at 345 Sandy Beach Rd. With a lakefront playground, shady benches, and plenty of open green space, it’s the perfect place to let younger kids run, climb, and play while you enjoy a peaceful view of Rock Lake.

There’s also a short, paved path along the shoreline — great for a little nature walk.

🧺 Bring: Sunscreen, water bottles, snacks, and a towel — just in case they want to splash by the shore!

☕ Mid-Morning Snack Break

After the playground, head downtown for a cozy break at Simple Kup Coffee Co., located at 123 N. Main Street. This locally owned gem offers great coffee, kid-friendly pastries, and a relaxed atmosphere. It’s open weekdays from 6:30 AM to 1 PM and Saturdays from 8 AM to noon — just enough time to recharge before your next stop.

🚶‍♀️ Late Morning: A Little History, A Little Art (All Ages)

From there, take a short walk over to Commons Park — the heart of Lake Mills — and grab a self-guided tour map from the kiosk. The Historic Walking Tour will take you past century-old homes, historic storefronts, and fun public art pieces.

Take breaks as needed — everything is walkable, stroller-friendly, and shaded by beautiful trees.

📚 Afternoon: Stories, Crafts & Cozy Corners (Ages 4–12)

No visit with kids is complete without a stop at the L.D. Fargo Public Library at 120 E Madison St. The beautifully restored building is worth a visit on its own, but the real treasure is inside — where the children’s area includes books, toys, puzzles, and play zones for a wide range of ages.

Throughout the summer, you’ll often find free drop-in activities, scavenger hunts, and themed crafts. Check their event calendar for specifics.

🍦 End the Day with a Treat

Wrap up your adventure right back where you started in Commons Park. Let the kids climb the playground one last time while you snag a hot dog, root beer float, or cone from Doyle’s Dogs, located just across the street. It’s the perfect way to wind down your day.
