Take a tour of the spring night sky with an amateur astronomer.
You don't need an expensive telescope to enjoy stargazing (though we'll bring one you can try out, too)! Enjoy an outdoor guided tour of the constellations and planets, gaze at the moon, and see and identify the moons around Jupiter. You will also discover some free tools you can use to explore astronomy in your own backyard.
*This event will still meet if the skies are partly cloudy, but we will need to cancel for rain or complete overcast.
**Before you arrive, please download, install and try out the free Stellarium mobile astronomy app. This is available on the Apple App Store, Google Play for Android, or the website stellarium-web.org. We will show participants how to use it to find their way around the night sky. Don't wait until you arrive to download the app; our cell service within the Natural Area is spotty.
Who Is Invited:
Ages 10 and up. Minors must be accompanied by their parent or legal guardian. No pets, please.
Reservations required! Reserve your spot at the Friends of Government Canyon website (see link above under ticket info). Registration opens on Saturday two weeks prior to the event and closes at noon the Thursday before the event.
This is a public program intended for individuals or families. If you would like to bring a group (Scouts, home school group, etc.) for a program at Government Canyon, please contact the Park Interpreter at [email protected] to schedule at a different time.
Where to Meet:
This activity meets at the Amphitheater, near the Frontcountry Trailhead. Lot C will be the closest parking. There is a gravel path leading from the parking lot to the amphitheater, a distance of about 120'. The amphitheater is near an accessible restroom.
How to Prepare:
Though the activity is free, entrance fees to the Natural Area do apply. We often fill to capacity. To ensure entrance and save time at the Fee Booth, please pre-purchase and print out a day pass. Day passes can be reserved beginning one month before the date of your visit. Please note: reserving a Day Pass does not guarantee a spot for you in this event! You must also register at the Friends of GCSNA website linked above.
Seating is on limestone benches. A blanket, portable chair, or stadium seat is suggested to make sitting more comfortable.
Dress for time outdoors, in layers that can be added or removed as the night cools off. Comfortable shoes and warm layers are recommended. Bring at least 32 oz of water per person.
If ADA assistance is required, please request modifications by emailing [email protected] at least 2 weeks in advance.
Cancellation:
This program is weather-dependent and subject to cancellation. Check trail conditions by calling GCSNA's main office at 210-688-9055, or go to the GCSNA webpage, Instagram, or Facebook.
