(DC) (National Zoo) Take a hike and join us for creative, drop-in play at the zoo! This week we learn about camping and trees to celebrate National Take a Hike Day on November 17th. Explore the wonders of the great outdoors through sensory play and art activities to help our young friends feel more at home outside in the natural world! Little Critters Nature Play is designed for ages 0-5 and their caregivers and families. Activities are designed with early learners in mind, but all ages are welcome. Parents and guardians must remain with their children.
