Recommended for ages 5 and up Ever wish that our Nature’s Playground was open later? Then join us for this special edition of Outdoor Adventures! We’ll open Nature’s Playground for an after-hours opportunity to climb, slide, and play. We’ll have lemonade and watermelon for a snack as well! Limited to 40 children. No organized groups or parties will be allowed to register. Please note that the remainder of the museum and grounds will be closed but the playground will be open for our lucky attendees.
