Exploring Around: one

Children begin the week by building a fort, which serves as a home base for a week's worth of adventure and exploration.  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!

This series includes various classes throughout the season. Please register for each individual class by using the links below:

WHAT TO BRING: Pack a backpack with snack, lunch, water, rain jacket, clothing for warm and cold weather, sunscreen, hat, and sunglasses. Wear sturdy, closed-toed shoes (no sandals).

HOW TO GET THERE: Please bike or walk to ACES whenever possible - it's not only fun, it saves the planet! Every time you come to ACES in something other than your own car (carpools work, too) you will receive a sticker to place on our Alternative Transportation Board. At the end of the season we will give away GREAT PRIZES including ACES classes, bike accessories, reusable bags etc. Make it a family challenge and have fun with it!
