Be Prepared
The Astronomy Festival is one of the most exciting and busy events and weekends at Great Basin National Park. Planning ahead of time will ensure you have the best experience during your visit. Check back at this page regularly for updates if event schedules change.
Tips for a successful Astronomy Festival visit:
Campgrounds will fill up quickly. Most park campgrounds are reservable up to 30 days in advance; Baker Creek Campground is bookable only one day ahead of arrival. Please visit the Lehman Caves Visitor Center or Great Basin Visitor Center for information on dispersed camping on public land outside of Great Basin National Park.
Fit into one car if possible. Parking is limited at astronomy events and you will be turned away if parking lots fill.
Bring red lights. White flashlights are not allowed at festival events in order to preserve everybody's night vision.
Bring plenty of layers. Telescope viewing can go well into the evening and nights get cold. Check weather forecasts as the festival approaches.
All events are free, but reservations may be required. Check the list below or the park's events calendar for information on specific events and if reservations are required.
Interested in volunteering? Our festival star parties are almost entirely volunteer run and registration is required to volunteer. Find more information at this link or further below.

Event Descriptions
Find details of each event during the Astronomy Festival below. Check the schedule above for dates and times of each event.
Telescope Viewing & Star Parties
Each night, amateur astronomers gather their telescopes near the Astronomy Amphitheater to showcase the night sky and dazzle with a peek through their eyepieces. Look at colorful star-forming nebulas, ancient star clusters, far off galaxies millions of light years distant, or the planets which dot our night sky.
Telescope viewing is driven almost entirely by volunteers donating their time and the use of their delicate equipment to the park. Treat volunteers and their telescopes with the care & respect they deserve.
Interested in being a star party volunteer at the astronomy festival? All that's required is a telescope and a passion to share with the general public. If you'd like to volunteer, please contact the Astronomy Rangers via email by clicking here. Pre-registration is required, and those who show up without registering ahead of time will be turned away. If registration is full, you may still contact us to be on the interest check for the following year.
The Great Basin Observatory peers into the night sky to help further new astronomical research and allow students as young as middle school to participate in science.

Guest Speakers
Each year we invite speakers from the professional astrophysics and astronomy realms to come speak about their research, projects, or their work. Stay tuned for updates on who 2026's guest speakers will be as we finalize the schedule.
Great Basin Observatory Tours
Tours of the Great Basin Observatory will be on a walk-up, first come-first served basis. All park program participants must check in at the Lehman Caves Visitor Center the day of the program. Limited to 15 people per tour.
Join a ranger to see the Great Basin Observatory the only research grade observatory in a National Park. Home to a 27-inch telescope, this observatory is used for research and education purposes. This program requires a 1-mile round trip hike on a gravel trail and paved road and standing for an hour. The Great Basin Observatory Tour is not wheelchair accessible.

Art in the Dark
Join Astronomy Rangers for an art project that experiments with how our eyes see color. This accessible and kid-friendly program will challenge artists to create and paint in low light conditions, under the guidance of the Astronomy Rangers. All needed art supplies will be provided.
Together, all will create a dazzling art piece in the Astronomy Amphitheater. These pieces will then be displayed for the remainder of the festival at the Lehman Caves Visitor Center for all to see and share in.

Astrophotography can be fun and rewarding if you can handle the cold temperatures and late hours required to get the perfect shot.
Don Riddle
Photo Workshops
Join an experienced astrophotographer and longtime Great Basin volunteer Don Riddle to learn the basics of night photography. Throughout the festival, Don will host events on photo editing, milky way photography, and nightly workshops to introduce astrophotography to all those interested.
These workshops are intended for beginner photographers looking to start exploring how to take nighttime pictures. Learn the advantages of various camera formats, exposure times, composition, and much more to enhance your ability to take beautiful night sky images. Registration will be required. Check back for updates as the schedule is finalized.
Equipment needed for evening workshops:
Camera (DSLR or Mirrorless)
Wide angle lens (stock lenses are ok. f stop lower than 3.2 is preferred)

Solar Telescopes and Crafts
Behind the Lehman Caves Visitor Center, rangers will have a solar telescope set up, allowing anybody to come and view our planet's closest star safely. View sunspots and prominences, filaments and ejections through our specialized telescope and see the sun as you never have before.
Next to the telescope, join in creating small, take-home crafts. Build a constellation using pipe cleaner and UV sensitive beads which change color under sunlight and glow in the dark. Perfect for all ages! No registration required, just drop by.
Note: If weather is poor, solar scope will be set up but the sun may not be visible.
Ranger Programs
Join park rangers as they present their astronomy programs in the dark of the Lehman Caves Visitor Center. Topics vary, but our dark sky rangers will guide you through the night sky, our relationships with the stars, and the protected dark of Great Basin.
Programs are free and require no advance registration, but the theater is limited in space. Some standing room is available.
Want to see some of these programs beyond the festival? Attend one of our many astronomy programs throughout the summer to see what our rangers have to share in addition to telescope viewing. Learn more here!
Accessibility
Have concerns about mobility or parking? What about bringing a service animal? Many questions about park programs and accessibility can be answered through our accessibility pages.
We strive to make every program just as easy to attend for every member of the public, regardless of ability. However, the nature of some telescopes make them impossible to view through without standing and balancing safely.
The best programs to attend for those with limited mobility will be:
All Ranger Programs and Guest Speakers
The Solar Crafts Table behind the Lehman Caves Visitor Center each day
Constellation Talks at the Astronomy Amphitheater each night
Art in the Dark the first night of the festival at the Astronomy Amphitheater
All may attend the Star Party each night and volunteers may have devices to allow those unable to stand or balance to view the telescope's focus. Great Basin Observatory tours are not fully accessible due to the stairs and gravel pathways leading to the dome.
Worried about making it to the Astronomy Amphitheater from the Lehman Caves Visitor Center parking lot? Speak with a ranger when you arrive and let them know. Limited parking is available for those with mobility issues next to the telescope viewing area and Astronomy Amphitheater.
Weather and Cancellations
September tends to be a predictably mild month, but rain & thunderstorms may occur. In the event of poor weather, events may be cancelled or moved and notice will be posted at the Lehman Caves Visitor Center throughout the weekend.
Indoor events will take place rain or shine
Outdoor events will be cancelled due to rain or thunderstorms
Keynote speakers will be shifted to Baker Hall with posted signage in case of rain or thunder. Ample seating is available.
Clouds alone will not cancel any events. Events will continue at their regularly scheduled times.
Volunteers
Telescope viewing is driven almost entirely by volunteers donating their time and the use of their delicate equipment to the park.
