The EcoTarium’s  Tree Canopy Walkway is open on weekends through June 21, then daily through August 16, weather permitting.  Kids and adults move through a series of platforms and rope bridges suspended high in the trees to explore life in the tree canopy (see photos)– and then zip-line down to the ground.  It’s open to children 5-11 years old when accompanied by an adult, as well as to children 12 and up with or without an adult.  Space is limited.  Purchase tickets at the museum.  The cost is $10 plus museum admission ($8 for members).  Check the website for preparation, safety information, and a liability-release form.
