    Worth a long drive to attend one of their spectacular star parties that happen most Friday nights! We were all the way down in Big Bend and drove 2 hours so we could attend and we are all so glad we did. Not only is the observatory itself so cool just to be there, but they also have a great visitor center with tons of informative displays, a great gift shop, nice bathrooms, and a very cool amphitheater outside where the star party begins. It was very cold over New Year's, and we unfortunately went when it was a full "super moon," so the moon itself was so bright that it was obscuring a lot, but the star guides did a great job. They told us about everything we could see and despite there being a lot of people at the star party, we never had to wait more than 5-6 minutes to look through one of the telescopes to see something they were aimed at. During our party we got to see Saturn, the Pleiades, a very cool shot of the moon, and a nebula. I have to admit I was so excited to be looking through telescopes at THE McDonald Observatory, and even if we couldn't see everything due to how bright the moon was I'm still so glad we went! 100% worth a stop, no matter how far you have to drive!

    The Hobby-Eberly telescope -- this guy is a giant, you can see it rotating from inside the viewing area. Super neat!

    McDonald observatory is such a cool place. We came on a Friday afternoon just to look around; it costs like $3 per person and you can do a self tour of the grounds. They have a little exhibit in the main entrance building which also has very clean bathrooms! And if you drive out to the main observatories (eg the hobby telescope) you can go inside and learn about the astronomy and some of the ongoing projects, including the Dark Energy project which is wicked cool. We ran into a staff member who very kindly offered to show us around a bit so we went inside one of the domes and he showed us the telescope. It's so crazy cool!! I can't believe the researchers and engineers also live way out here on the property but they do, there are houses there on the grounds. It's such a neat and beautiful place, I would highly rec a visit and hope I can make it back for a Star party sometime (it was too late in the evening for us to attend, they start at 8:15pm and cost $20 I think? But sound so neat!).

    This is a great visit if you have an afternoon and evening to be in the area. I made reservations a week prior for a guided tour, a solar viewing, and the evening Star Party. I showed up at 12:30 pm and the Solar Viewing started at 1pm and lasted about 45min. It included a great presentation about the sun and included live feeds from their solar telescope with lots of great information. Very cool! At 2:00 pm the guided tour starts with a brief overview of what to expect and then a trip up to the two biggest telescopes they have with a detailed discussion of how they work and how they are used. They do not have any daytime viewing but the tour was excellent. The entire tour lasted about 2 hours. There is a 4 hour break before the Star Party starts. Sign in between 8:30-9 and the program starts at dark around 9:30 this time of year. We had some clouds come in but we did get a little time on the telescopes and then went inside for a "make up" presentation that show slides of what we were supposed to see. Even missing out on a full 2 hours of telescopes the program was fantastic. The staff is great and their passion shows for what they do.

    A special experience awaits you at one of the McDonald Observatory Star Parties. When planning my trip out here, the observatory was a must-visit. All my life I've been reading about it and i wasn't going to miss it. You must make reservations to look through the telescopes. Refer to the website. Fortunately, I snagged a reservation and now all I had to do was hope the skies were clear on my nite out. Lucky me. After a few days of partly cloudy, the skies mostly cleared up and I headed up to the observatory. They time the star parties as they call them, to coordinate with sunset. Located in the Davis mountains, this is the highest point in Texas! A first for this Texan who has lived here all his life. A staff memeber\researcher\Post Grad student begins the presentation just before sunset. Guests which number about 200, gather in a beautiful stone bench amphitheater under the Big Texas sky. Relating the history of star gazing in the area, pointing out constellations and planets, it was infinitely more interesting than i had imagined it would be. The presenter had a giant hand-held green laser about the size of a large flashlight. He used this to point out things in the sky, which was amazing. After about 45 minutes the guest are released to gather and look through 6 different telescopes of different magnifications. Even the smallest is probably larger than most will ever look thru. Fortunately, two of the dome-housed big telescopes were used allowing us to see nebula and constellations with incredible clarity. it was more than chilly and cold as the night wore on but a beautiful experience. If heading this way be sure and make time to visit the University Of Texas McDonald Observatory. A Big Huge Definite... G0!!!!

    Loved it!! Star party is a must! Solar viewing and guided tours during the day a must! Our guide was Abby and she was the best for all ages. So patient and smart! I learned so much! Excellent for families.

    I have to admit that I'm not a big astronomy fan. It's cool but just not really into it. We scheduled the solar tour which was at 1 pm which is 45 minutes. By the time we tried to book the star party it was full so yes you must plan ahead. It was a great presentation about the sun. I learned a lot but my husband knew most of the info. I naively assumed we would get to look through a telescope which was not the case. She live streamed it. Although my husband was not surprised. But great facilities, friendly staff, nice gift shop, and self tour. You can totally geek out or just do a quick tour like I did. The drive was so gorgeous. Who knew we had such pretty mountains in Texas? And now I can say I've been there! Bucket list.

    Make sure to plan in advance because reservations fill up fast. And if they are full, don't be disheartened - add your name to the waitlist and stay optimistic. That's how we finally got tickets to the evening sky viewing and just a couple of days before we were going to be there, we finally snagged two spots for the star party! The two experiences are different and complementary, so if you can stay late, definitely book both! The host was humorous, engaging and informative. It was really cool to spot constellations and learn so much about the night sky. The star party actually throws up some real-time telescope images, which was also such a special experience! Oh, it does get really cold up the mountain, and the entire programming is outdoors of course, so be prepared! If you have a pair of binoculars, bring it.

    Worth the trip. Far out and beautiful. The Star Party was amazing. Clear sky initiative in use to showcase constellations and nature's beauty. Museum is fun and educational. Must see!

    I usually don't like to leave a bad review, but we came for the star party, and had bought our tickets weeks prior. Upon arriving and entering, before even hello or welcome, the blonde woman checking folks in was bluntly rude, "hello unfortunately we don't allow pets" when indeed my dog is a service animal and when i told her she got attitude "well then i got some questions for you" and i answered them politely and she gave attitude, as the woman next to her on the laptop checking us in was very welcoming. Very rude woman. The gift shop prices were a bit over priced, and although we weren't able to go into observatory's or see anything because of the weather, we gave two stars because they did allow us to get a refund. Not much variety for drinks or any snacks. Everything they speak or talk about is available online - so if there is a star party that's not allowing viewing but indoor movie and talking it isn't worth it. The outside crew working were very nice and friendly and all loved my service animal. My service animal was more behaved than any of the children in attendance who were bored, impatient and lack of interest in the event.

    McDonald Observatory was incredible! If you can go for a star party, do it as you get to learn about constellations and look through some of the smaller telescopes and a few in the domed observatories with their dark skies! So many stars on this clear night! I then went the next day to do a tour of the 107-inch telescope which was so cool to see. I geeked out a little here. There aren't a whole lot of observatories open to the public so McDonald tours fill up quickly from people from all over the world. It was a highlight of my trip.

    Busted!

    Not doing a little upfront research sucks. Thank goodness for a bit of a self guided tour, otherwise the visit would have been a bust. If you plan to visit, be sure to BUY YOUR TICKETS ON-LINE, well in advance of your visit. We did duck into a rather interesting presentation (on the sun), but in retrospect I think it was part of the tour we did not have a ticket for. But there sure was enough room in the room, so I don't really think it was a problem. Surprisingly there is a cafe here, and a rather nice gift shop. The main reason for my rating not being higher is that many of exhibits were broken (see photos, to be up loaded shortly). After looking at the exhibits we jumped in our car to visit the telescopes. There are several large domed telescopes here, and you can visit (at least) two of them. They are impressive to see. You can peer through a glass window and see all the workings. Would have been neat to see, real time, through one of the telescopes. Ah, for the lack of planing. Bottom line: Do plan ahead! PS. Three star rating (A-OK) is because of so many broken exhibits. If it wasn't for that, it would have been four stars. I won't be a fan (4 stars), or better, until I actually get to take a tour. Rating not affected by lack of planning on my part.

    Milky Way taken about 4 minutes from the observatory

    We've been out to 2 star parties here and they were both wonderful. It was shocking to see them point out the obvious light pollution from the Permian Basin when we went a few weeks ago, I went out and got some Milky Way shots and the light provided from the oil fields was obvious in many shots. Go here, educate yourself up, sit under the stars and breathe. Let's find a way to keep this place dark, too.

    Cool socks for sale in the gift shop!

    See all

    Ask the Community - McDonald Observatory

    We know there is not overnight RV parking but is there any bus/large vehicle lots since we would still be hitched to our trailer for the star party event?

    Yes they do have bus parking, n rv should fit

    Is there any discount for disable veterans?

    They only list military/senior discount. They're not specific on either active, guard, reserve, veteran, retiree, or disabled veteran. Hope this helps.
