Dark Texas Skies introduces cosmic adventurers to the stars with two large observatory grade reflector telescopes. Oberwerk BT-100XL-ED and BT-127XL-SD binoculars are also used to view larger celestial objects, which are mounted on top of state-of-the-art “Go-To” instruments. Whether you are a seasoned astronomer or a newcomer, you will enjoy using our equipment.
Dark Texas Skies is located at the Marathon Motel & RV Park in Marathon, TX. This establishment has been featured on Texas Country Reporter and in magazine & newspaper articles because of its many amenities and its stunning nighttime canopy of stars.
Below is a map where Dark Texas Skies meet nightly. We gather outdoors at the Visual Observatory, about 150 feet behind Room 8 of the Marathon Motel & RV Park. Admission is $10.00 for adults and children are free younger than 18 years old.
Star parties are scheduled every night of the calendar year (including holidays) if the weather permits and the date is NOT indicated by a red marker on the Moon Phase Calendar. We begin at sunset if the Moon is visible, otherwise we begin 1/2 hour after sunset.
How Dark
Is Dark?
Dark Texas Skies boasts a very dark nighttime sky. We are located in one of the darkest areas in the lower 48 contiguous United States!
track & see the ISS
Guests are notified when the International Space Station flyover occurs. The ISS usually appears very bright as it glides across the night’s sky at 17,500 mph as it orbits every 90 minutes at an average altitude of 227 nautical miles above the Earth.
The real-time NASA tracker shows where the International Space Station is right now and its path 90 minutes ago (-1.5 h) and 90 minutes ahead (+1.5 h). The dark overlay indicates where it is nighttime in the world.

Testimonials
We visited Dark Texas Skies on recommendation from the Alpine Visitor Center. Bill and Andy were excellent hosts and teachers. We had unlimited telescope time, coupled with excellent teaching and guidance from them. We showed up at dark, and were able to experience unbelievable views of stars, planets and constellations. Well worth the $10 fee per adult and free to children. We were delighted with this experience. We will be back!
- Steve Hart
A special feature, which we were informed after checking in, was a nightly star gazing party, weather permitting. The hosts, Bill and Andy, were fantastic. They explained things about the night sky, the stars, and the seasons, among other things. We will definitely be back.

The place is amazing. The sky is magical and Bill Ramey absolutely made my stay to be even better. Actually, I was supposed to stay one night but after meeting him, I ended up staying 4 days and still felt it wasn't enough. He is an astrophotographer and amazing person!

We decided to stay In Marathon, a tiny little town in west Texas on hwy 90 outside of Big Bend National Park at the Marathon Motel and RV Park and Skypark. They happened to have star parties almost every night by two astronomy enthusiasts, Bill and Andy. They were so informative, and their enthusiasm was contagious. If you are in the area, I highly recommend experiencing the beautiful night skies at Dark Texas Skies.

We only had one night here and what a night it was!! Marathon is a Dark Skies area, so they ask that you keep your curtains drawn and exterior lights off at night. Which seems a little inconvenient until you realize just how much of the night sky you can see with so little light pollution. Then Bill and Andy pull out the telescope and binoculars! The park houses two large telescopes. The night we stayed, we were able to see the moon, Jupiter, Orion Nebula, a comet, Starlink satellites, the twin stars of Gemini and so much more! Andy and Bill share so much of their knowledge about astronomy and it’s such a cool experience! The park and facilities were clean and quiet. Everyone there was very friendly and we were able to use our Passport America discount! It’s also a short drive to downtown Marathon. We are already planning to stop here again!

I did both the McDonald Observatory and Marathon Motel & RV Park star parties in the same month last fall. Trust me, the Marathon party was far better - certainly more informal and therefore more fun, but the guys running the telescopes were much more informative about what we were looking at than the grad students at McDonald ("uh, I don't know which of Jupiter's moons those are.") Their enthusiasm for the stars is infectious, they KNOW what they're showing you, and they'll keep showing you more fantastic things as long as you're willing to stay out and look at them (unlike McDonald).

Bill AND Andy are INCREDIBLY informative and enthusiastic about the night sky offerings in the Big Bend Sky. I learned so much in just over two hours. We had tickets for the McDonald Observatory and gave those up for the opportunity to hang out for individual attention and expertise about our night sky. I look forward to the opportunity to come back on a non-moon night so I can SEE MORE! My family and I saw planets, moons, stars, constellations, nebulas, and OTHER GALAXIES! Come to Marathon to see the local mountains on earth AND parts of our universe. Giddy amazing-ness (if you geek out over this stuff like I do) is in your future if you check out this gem of an experience. 🤗
Again, THANK YOU Bill and Andy!

We came to the star party tonight and it was super cool! We chose a night when the moon was really bright, so Bill and Andy said that this isn't the best time to view the night sky, but we still enjoyed it immensely! They make you very comfortable using the equipment, they answer all your questions and educate along the way. Their knowledge just blows my mind! I would recommend this to anyone and everyone! Best money I've spent in a very long time!

I had a great experience with the star party! Bill is very knowledgeable and eager to answer any questions regarding Astronomy (or have a casual conversation with). This is a must-see experience for anyone who loves the sky, stars, or space! This was my first time seeing a dark sky, and I wouldn’t want it in any other place!

A great highlight of Marathon, TX. Very informative for all ages. Spectacular views of the prettiest night skies I have ever seen. Telescopes were great for viewing planets and stars.

This may have been the highlight of our trip to Big Bend National Park. We are so grateful to have experienced what turned out to be a spectacular display of stars. Looking through the telescope and binoculars on a peaceful night, we enjoyed the friendly and enthusiastic information provided by Bill and Andy. It was a thrill and considering the price, an unbeatable experience. Anyone who visits the Big Bend area needs to put this on their agenda!

Andy and Bill, you guys are amazing! I had a stellar time at the stargazing party last night. I learned so much. If this were what school was like, I’d have loved it so much more. The tent camping was perfect. Beautiful sunset and sunrise. But the star party was the highlight. You are equal parts edifying and entertainment. Thank you for sharing your passion with the rest of us!

Everything and everyone here is a amazing! I had the entire tent camping area to myself, complete with a pond with lily pads and frogs quietly croaking through the evening and night. Would be great for a group with its outdoor kitchen area. I took a sunrise stroll and checked out the grounds—beautiful central courtyard with a fireplace and fountain . . . And the stargazing party!!! Bill and Andy were incredibly knowledgeable AND entertaining. They could host their own astro tv show. I’d watch. And I don’t watch TV. Such a unique and unforgettable experience.

Always the best place to stop on the way to Big Bend. The kindest staff, great atmosphere, and a stellar nightly viewing of the beautiful Texas sky with two dedicated astrophotographers! The place has so much personality!

A fulltime resident astrophotographer, name of Bill Ramey, rolls out a 20” Obsession and a 13” homemade Dobsonian telescope for park visitors to gaze through almost every clear night. Bill was very accommodating, knowledgeable and friendly, and I highly encourage you to go to one of his talks if you stay at the park. The night I took the short walk over to the big scope he treated us to wonderful views of M13, the great globular cluster in Hercules, M51, a pair of interacting galaxies in Canes Venatici, and a spectacular view of M81 and M82, a galaxy pair in Ursa Major.

Beautiful common area with fire place and seating for hanging out. Best thing though is the star shows. Various optical instruments including 20" telescope and people who know how to use them. Highly recommended.

This area is a dark skies area and the residents take that seriously in Brewster County. The owners of the RV park/motel are into telescopes and astronomy. There were telescopes and people to explain what you were seeing during all the clear sky night. That was one of my favorite parts of this experience.

Friendly staff and beautiful views of the mountains on the horizon. This RV park has a special on-site astronomer and large telescope for star viewing. This isn't amateur hour. We saw Jupiter, Venus and Saturn even had its rings visible. Absolutely amazing experience in the "Dark Sky" park area where the night sky comes to life!

We stayed at the Marathon Motel to see the stars. The room was clean and comfortable, no frills but had everything needed. Staff was very nice. Had a concrete pad for the telescope gear and enjoyed the star parties through the big scopes. Can't wait to come back out.

We usually stay at hotels with pools but this time everything was booked fortunately for us! It was a different experience for our kids, the cottage was cleaned and cozy, they have a restaurant outdoor with a very inviting atmosphere, distance between tables and great service! At night they showed us the stars and the planets! Our kids were thrilled when they saw Saturn, Jupiter and Mars! They also lit up the fireplace for us to enjoy the night! We highly recommend this motel!

This place is incredible. It is an experience beyond what you'd expect from the name. The owner, Danny Self, is wonderful and provides more than a place to stay. Did you know they have a legit, professional observatory? Well, they do!! Spent the night looking at Jupiter and Saturn plus learning about astronomy from their resident astronomer, Bill. Honestly, how many motels actually have their own astronomer?!

We really liked this park. They had a Star Program and a gentleman showed us Saturn, Jupiter and the Moon on his large Newtonian telescope(we had to use a ladder for some views). It was awesome. We accessed Big Bend Park from here although it makes it about a 50 minute drive just to get there.

Such a beautiful little get away spot. The owner and staff are extremely friendly and I had fun using their large telescope and learning about astronomy. One of the most peaceful places I've been lucky enough to visit.

This is where Wim Wenders shot the famous Paris Texas. A superb setting surrounded by the rugged semi-desert of South West Texas. The park is one of the nicest we've come across on our 3000 mile cycle journey. Loved the camp site, the amenities are great and the camp managers friendly, welcoming and helpful. We were luck enough to be there in mid April on a moonless night, and Stargazing is a must. It's a class 1A night sky and if you are lucky because of the weather, the local astronomer will be out for a talk and telescope viewing. Great stay, highly recommended!

Beautiful place. Quaint little town. Star gazing is excellent. The man at the rv park has a set up that is absolutely amazing for looking at the planets and he sets it up for the campers to learn and enjoy.

We just stayed one night here and were impressed by the cute features of the Marathon Motel and RV Park. The camping spot itself is just an open gravel parking lot with hookups but they have very nice grounds that include a beautiful grassy courtyard, outdoor restaurant, pond, chicken coop, and the best part: a telescope and a really knowledgeable astronomer who is there to point things out!

Marathon was beautiful. The sites are pretty level, almost all of them have 30/50 service now. The work they have done to the courtyard, motel, and sitting areas make this a very comfortable place to relax. The staff is extremely friendly, and at night they have star watching sessions through some of the large telescopes they have on-site. Marathon is a designated dark-sky city so the views are not obstructed by the glow of lights.

The RV spots are maintained well, and the motel rooms are impeccably clean. Danny, who owns the place, is a blast and he obviously takes great pride in the Park.
Each evening there are "Star Parties" hosted by Bill who is the resident expert on all things Astronomy. There are high powered telescopes onsite that Bill will help you use.

Intending on a short overnight stop over on our way to Marfa, we decided to extend our stay by two days. The grounds are lovely with a beautiful courtyard that is perfect for an evening drink and conversation. The RV Park has everything a traveler needs, plus super accommodating and friendly staff. We also, had the neat surprise of being invited over to the Marathon Sky Park for a breathtaking view of the sky through a powerful telescope and a knowledgeable guide, Bill. It was definitely a serendipitous experience.

Bill and Andy were amazing Star Party hosts. We used the provided 10" and 20" Dobsonian telescopes with premium lenses to view several planets and much more.

Had we not been so tired from our Big Bend hikes, we would've stayed up all night with Bill. His knowledge was amazing, he allowed us to ask all of the questions and he did a great job of answering them in a way we could understand. The sky was magical. We were so glad we made the walk down the road to spend the evening looking at the Dark Texas Skies. If I had a suggestion it would be for the owner of the motel, it sure would be nice if you would turn the lights off of the trees at night or at a minimum, put up down facing lights.
Thank you Bill for a great evening.
THE Place to be After Dark
The Marathon Motel & RV Park is a safe place to be after dark. The facilities accommodate those who desire motel lodging, arrive in a RV or prefer to bring their own tent. And you are only a few steps away from Dark Texas Skies to discover a world of nocturnal starry wonder!
