As spring evenings stretch longer and warmer, Bernheim comes alive in unexpected ways. Dusk invites frogs to sing, fireflies to glow, and nocturnal creatures to stir. These twilight hours open a window into a world that’s often overlooked — one filled with quiet magic, wild beauty, and the thrill of discovery after dark.
This spring, we invite you to explore the forest under the stars through a series of unforgettable nighttime experiences. Whether you’re seeking quiet reflection, curious exploration, or family-friendly fun, there’s something for everyone. Here’s what’s in store:
Full “Flower” Micro Moon Hike
May 12 | 8:30 – 10:45 p.m.
A micro moon — when the full moon appears smaller and dimmer due to its distance from Earth — creates a unique opportunity for skywatchers and nature lovers alike. Explore spring’s nocturnal rhythms with a moonlit hike full of mystery, sound, and science.
