Exploring Around 1

Children begin this class by building a fort, which serves as a home base for continuing adventures into the wild world surrounding Hallam Lake. Natural history, art, and storytelling are mixed with plain old fun and a sprinkling of surprises. Come join us for a week full of adventure!

Please pack a backpack with lunch, water, rainwear, clothing for warm and cold weather, sunscreen, a hat, and sunglasses. Wear sturdy, closed-toed shoes (no sandals). Kid's feet might get wet while exploring around so please put an extra pair of shoes and socks in their backpack. Parents are invited to the parents' party on Friday at 12:30pm!

Meet at ACES' Hallam Lake Nature Center at 9am!
