Delight in our annual autumn experience as fireflies guide you on our trails to encounter larger-than-life costumed nocturnal creatures. Hear stories from a Great Horned Owl, observe the acrobatics of the Flying Squirrel, go batty with Little Brown Bat, and meet a real-live creature of the night! Come in costume for twice the fun. This event takes place outdoors, even if it’s raining. Registration required. $6 member; $10 nonmember; under 2 is free.
