Whether you’re looking to enjoy a peaceful walk through the trails, discover native plants, spot local wildlife, or spend meaningful time outdoors with family and friends, there’s something for everyone.
Each event throughout the week offers a unique way to experience the beauty and importance of our environment, from guided walks and hands-on activities to community gatherings that support conservation and education.
By participating, you’re not just enjoying nature, you’re helping protect it. Your presence supports our mission to preserve these special spaces for generations to come.
Take a look at the events below and plan your Earth Week adventure with Hawthorn Hallow. They hope to see you out on the trails!
Lyrid Light Show-Wed, April 22 at 9 pm
Join at the Heide Observatory for the Lyrid Lightshow, a classic spring meteor shower known for fast-moving meteors and the occasional bright fireball. The Lyrids originate from debris left behind by Comet C/1861 G1 (Thatcher), which Earth passes through each April as it orbits the Sun. While the Lyrids do not produce the high hourly rates of some summer
meteor showers, they reward patient observers with quick, sharp streaks that can appear anywhere across the sky, often flashing suddenly rather than leaving long trails.
Tickets include the use of our anti-gravity chairs, allowing guests to relax comfortably while observing. For best viewing, guests are encouraged to face away from artificial lights, allow their eyes time to adjust to the darkness, and scan large areas of the sky rather than focusing on a single point. Observatory staff will share tips on where to look, explain why
meteor activity can vary throughout the night, and discuss how comet debris creates these fleeting streaks of light.
Meteors are unpredictable by nature, and viewing success depends on sky darkness and atmospheric conditions, but even a handful of sightings can make for a memorable experience under the stars. $15 per person, more info and registration at https://www.eventbrite.com/e/lyrid-lightshow-i-tickets-1978293689680?aff=oddtdtcreator
