Under the Stars: Exploring the Greater Big Bend International Dark Sky Reserve
There are few places left in the world where the night sky still looks like it did a hundred years ago. In Far West Texas, we are lucky enough to call one of those places home. The Greater Big Bend International Dark Sky Reserve is the largest dark sky reserve in the world—spanning more than 15,000 square miles across the Texas Mountain Trail Region and northern Mexico. When the sun dips behind the mountains, something extraordinary happens here: the Milky Way explodes across the sky, planets shine bright enough to cast shadows, and countless stars remind us why this is one of the most awe-inspiring places on Earth.
What Makes This Sky So Special?
The Greater Big Bend International Dark Sky Reserve encompasses a sweeping stretch of the Chihuahuan Desert, including Big Bend National Park, Big Bend Ranch State Park, and the communities of Alpine, Marfa, Fort Davis, Marathon, and Terlingua. In 2022, this vast area was officially designated as an International Dark Sky Reserve—one of only a handful in the world.
Unlike many places where city lights drown out the stars, this region’s low population density, commitment to responsible lighting, and clear desert air combine to create some of the darkest night skies in North America. On a moonless night, you can see more than 7,000 stars with the naked eye.
Best Places to Experience It
McDonald Observatory, just outside Fort Davis, is one of the best places in the world to stargaze. Their famous Star Parties bring visitors from around the globe.
Big Bend National Park offers world-class dark skies. Step away from the campground lights, let your eyes adjust, and you’ll witness the Milky Way stretching from horizon to horizon.
Big Bend Ranch State Park is perfect for those who want to combine rugged adventure with night-sky wonder.
Protecting the Dark
This designation isn’t just an honor—it’s a commitment. Communities across the region have worked together to reduce light pollution, switch to shielded fixtures, and educate residents and visitors alike about preserving this natural treasure.
Every light we dim helps protect the delicate balance that makes this starry sky possible—not only for us, but for wildlife and future generations.
Plan Your Own Stargazing Adventure
You can see the stars from just about anywhere in the Texas Mountain Trail Region!
Check moon phases for the darkest skies (around the new moon).
Step away from bright lights and put your devices away for 30 minutes to let you eyes fully adjust to the dark. Bring a red-light flashlight to preserve your night vision.
Pack a blanket, lie back, and let the desert sky put on a show.
For an unforgettable professional stargazing experience, visit the McDonald Observatory in Fort Davis or the Marathon Motel & RV Park in Marathon—both offer exceptional opportunities to take in the night sky with expert guidance and top-notch viewing conditions.
Why It Matters
Stargazing in Far West Texas isn’t just about the view. It’s about connection—connecting to our history, our environment, and the sense of wonder that drew early people to look up at the same stars. When visitors come here, they’re not just exploring a place. They’re experiencing the night the way it was meant to be.
The Texas Mountain Trail Region is proud to be part of this global effort to keep the stars shining bright. Whether you’re an amateur astronomer, a night photographer, or just someone who needs a little wonder, this is your invitation to look up.
