Get ready for fun! On Saturday, June 27, Nichols Arboretum transforms into an open-air playground where kids and grown-ups can explore, create, and play at their own pace. Big Play Day is free and drop-in, arrive anytime between 10 a.m. and 2 p.m., and let curiosity lead the way. With a blend of open-ended nature play and hands-on exploration, Big Play Day celebrates the pure joy of playing outdoors, meeting new friends, and discovering fresh ways to move, build, and imagine. Whether you’re weaving a bird’s nest, pounding a drum, or turning sticks into sculptures, every activity invites playful discovery.
