Come celebrate summer by cooling off at the nature center with activities down at the Middle Patuxent River! Bring your own non-perishable picnic, and join a Robinson Naturalist at the river for lunch and fun, family-friendly river games. Search the stream for big and small animals! Make boats and race them downstream! Come dressed to get wet. You’ll wade in the river so wear closed-toed water shoes. Participants must check-in for program at front desk. Participation is limited to 25 people per program. Online registration not available; please call 410-313-0400 to register.
