Grasshopper Grove is a ‘bridge’ between a mowed lawn and the wild woods, that inspires children to discover nature play spaces in their own backyards and the wider world. Natural elements are at the heart of child-centered play. They have the opportunity to experience things that many children miss out on in today's over-scheduled and technology driven world. In Grasshopper Grove, children will be encouraged to explore this world around them, get dirty and above all, have fun! Children can use their imaginations to build in the ‘loose parts’ area, and combine a slab of slate, rainwater and a paint brush to create an artistic masterpiece. They can hop from stump to stump, play in the sand and dirt pile and more! These simple activities strengthen hand-eye coordination and muscle development while fostering creativity, critical thinking, appropriate risk-taking, problem solving and cooperation which are all critical to healthy childhood development. Grasshopper Grove is open seasonally from Mid-April through Mid-November.

The Gem Mine

Howdy Y'all, we are excited to bring Educator (Prospector) Adam's "Gem Mine" to Grasshopper Grove! After you purchase your bag of treasure at the check-in table, you'll borrow a sand sifter and make your way to Grasshopper Grove. Then head to the water feature to sift or "pan" through the sand to uncover what's inside... including unique gemstones and possibly a gift token to the Gift Shop (located at the Wildlife Education Campus)! All proceeds from the Gem Mine support the care of the the animals at the Wildlife Education Campus.
