Summer Starparty Program

Since 1995, the HVAG has conducted a summer starparty series at the Halley Hill Observatory. The park campground is often filled to capacity for some or all of these events and turn-out has been excellent. Please check our calendar for this years HHO events.


The Halley Hill Observatory is located adjacent to the Grant Park main campground. To reach the observatory from the campground, follow the path across from campsite 22. The observatory is at the top of the hill.


To make your visit to the Halley Hill Observatory more enjoyable, please follow these simple guidelines:

Turn off your flashlights when you reach the observatory. Bright flashlights keep your eyes from adjusting to the darkness and make it harder for you, and others, to see astronomical objects.

Make sure your children are carefully supervised. It's important that young children stay with a parent or other adult at all times. Follow the observatory docents' instructions.
