What if the most important classroom had no walls?

At The Wonder Grove, we believe it does. It's a meadow, a mud kitchen, a patch of grass where a toddler finds their first roly-poly and a kindergartner builds their first dam. It's joyful, it's boundless, and it belongs to every family no matter their income, zip code, or background.

We're a nonprofit outdoor children's museum rooted in West Sacramento, and we're on a mission to make nature and play accessible to every child in our region.

What we do

Every month families gather for Wiggle Worms Nature Play, our free, drop-in outdoor program for children and their caregivers. No registration. No fee. No barriers. Just fresh air, open-ended exploration, and the kind of messy, magical play that builds brains, bodies, and belonging.

In 2025 alone, we welcomed more than 1,000 participants through Wiggle Worms. This year we are launching our nature play straight into classrooms with our mobile schools program and Family STEAM Nights, reaching children who might never otherwise get to dig in the dirt, build with sticks, or watch a caterpillar crawl across their hand.

Where we're growing

This year, The Wonder Grove is growing roots in a new way. As First 5 Sacramento Equity in Action grantees, we are expanding our Wiggle Worms Nature Play to parks across Sacramento County. We are strengthening our organization foundation to expand our reach, deepen or impact, and continue working towards our permanent home - a real, rooted outdoor children's museum!

But growing takes fuel. And that's where you come in.

Why your gift matters

We keep our programs free on purpose. We believe access to nature and joyful play shouldn't come with a price tag. Your donation is what makes that possible.

Every dollar you give goes directly to:

🌿 Keeping Wiggle Worms free for every family
🐛 Supplying materials for hands-on nature exploration
🌱 Supporting our mobile programs in under-resourced schools
🌳 Building toward a permanent outdoor museum space

Give today. Grow with us.

The Wonder Grove is small, mighty, and just getting started. We're building something that this community will be proud of, a place where every child can dig in, look closer, and fall in love with the open skies and shout into the breeze.

We'd be honored to grow it with you.
