Nature outing "The little world of the night: bats and starry skies" at the Domaine de Chaalis

The Regional Natural Park and the Domaine de Chaalis invite you to immerse yourself in the world of the night. At dusk, the discreet yet fascinating creatures of the night will reveal their secrets. Discover their incredible sensory abilities and listen to them using ultrasonic detectors. Then, turn your gaze to the sky to (re)discover the beauty of the night sky: time to observe the stars and constellations.

Evening hosted by the CPIE des Pays de l'Oise and by the amateur astronomers of the MARS 60 association.
