Every summer, amateur astronomers gather at Indian Trail Spring in the Ochoco National Forest, located 45 miles east of Prineville, Oregon, for the Oregon Star Party. We go to this remote location for the very dark skies, low humidity, and wonderful nighttime viewing.
In partnership with Ochoco National Forest, Oregon Star Party is a nonprofit organization staffed entirely with volunteers. Operating under a permit issued by the US Forest Service, Oregon Star Party is spread across 55 acres at Indian Trail Spring. This is a primitive site with an elevation of over 5,000 feet and an unobstructed 360 degree horizon. Oregon Star Party is considered to have the darkest skies of any major star party in the continental United States.
Each year, OSP’s volunteer planning committee plans youth and adult activities, secures door prizes, and arranges for vendors to sell their wares during the five day long event. Onsite amenities include portable toilets, trash receptacle and food service. Volunteers staff the entire event, including a first aid crew.
Please see our registration page to sign up for a volunteer shift.
Amenities
Porta Potties – OSP has Porta Potties throughout the camping areas, arriving Monday afternoon through Sunday. They are pumped daily.
Trash – A trash dumpster is available on the 800 road near the entrance to the event. Please deposit trash and garbage during the week or when you leave OSP.
Water – We are a dry camping site. Bring your own water to OSP. One gallon per person per day is typically sufficient. If we have hot weather, that may increase. OSP volunteers will have water available during their shifts, so if you volunteer during the event, bring your own bottle.
It is very important to stay hydrated at OSP’s dry desert environment. Our first aid people’s typical response is due to heat exhaustion incorporated with dehydration.
FAQ for Oregon Star Party 2026
1. Where can I take a shower?

There is also a playground in the park for the kids to play.
Crook County Swimming Pool
399 NE Garner St, Prineville, OR 97754
2. Do I have to wear a mask?
Masks will be optional at our event, but highly recommended to protect those of our attendees who have chronic, serious health issues. Please respect those who choose to wear them.
3. I’m driving my RV-5th Wheel or Bumper Pull or RV Trailer. Can my spot be reserved?
RV spots are first come first served.
RV and trailer spots are allowed on the 800 and 802 roads only.
Please make sure you come up with empty grey and black water tanks. Water dumping is not allowed up at the camping area due to forest service rules.
4. I want to buy ice. Can I preorder?
YES!
Ice pre-ordering is available during registration. You may be able to buy ice at the event but there is a limited amount for sale during the star party. Ice is on a first come-first served basis.
When the ice is gone, it’s gone.
5. What is the artwork for 2026 OSP?
Congratulations to Sara B. for the artwork gracing our merchandise this year
If you’d like to be part of the artwork for next year, watch for emails, notifications on facebook or the website for more information about the artwork contest. 2026 artwork contest opens in the fall.
6. If I don’t register early, can I still attend the event?
Yes, but with limitations and other issues.
1. If we reach our maximum number of attendees, we will not be registering additional folks on site. This happened in 2017 for our event due to the eclipse. The forest service has a limit to how many attendees we can have based on our permit.
2. If you register early, you can pick the size of the merchandise you purchase and dinners.
After early registration closes, if we have merchandise available, you may be able to purchase them onsite. Merchandise can be purchased at our sale on Thursday. Availability may be limited or nonexistent.
7. Can I get a discounted registration if I only attend a night or two?
We do not offer a discounted or ‘by the night’ registration.
8. You ask for people to volunteer at the event. Why should I?
OSP is a great opportunity to volunteer to help make our event run smoothly. Our volunteers are what make OSP happen. Many hands make light work. Our entire committee is made up of volunteers who proudly attend zoom meetings all year to make this event happen for you.
You might have an opportunity to meet people you might not get a chance to meet otherwise. Follow the button below to sign up:
We would love to have you on site to help us make OSP a success again this year. If you preregister, you’ll see a link for signing up for volunteer shifts. You can also follow the link above.
9. Is internet available? How’s the cell service?
OSP does not provide internet service. Indian Trail Spring is remote and cell service is carrier dependent and spotty, at best. We cannot guarantee you will have cell service. OSP will have access to the internet through the generosity of a committee member.
In 2025 we had a member generously donate his Starlink internet for attendees to use. We had tables set up for attendees to lounge and enjoy.
Organizers arrive at the onsite location ITS, usually a day or two before the event. They won’t be able to answer questions or post notifications on Facebook, Cloudy Nights, or our website. We are very busy during the event to post information.
10. I want to bring a generator to charge batteries or run my air conditioner in my RV. Can I do that?
YES!
You can bring a generator. We do have a policy for using your generator. You’ll receive this information in your packet when you arrive at the star party.
11. If I want to help during the year, how do I do that?
You can be part of the committee at three levels, volunteer, associate or full committee member. You don’t have to have astronomy expertise to be part of the committee.
We would love to have you. If you’d like to join us, please contact us at:

We look forward to seeing you this year, 2026 for another great summer of dark skies and astronomy!
