Participate in The Children and Nature Network’s Let’s G.O.! (Get Outside) initiative to get intergenerational groups outside together. Join us at the Nature Center for a fun, earth-friendly afternoon as we spruce up our grounds, prepare our garden beds, clear our trails and more. Learn about sustainability practices from our naturalist staff. Free visit to the Animal Museum for all Earth Day volunteers. Groups welcome but pre-registration required.
