About Big Bend Ranch
Big Bend Ranch is the biggest state park in Texas and sits in the darkest patch of the entire state — the Trans-Pecos, on the far side of nowhere from anywhere with streetlights. Pair it with neighboring Big Bend National Park and you're standing in one of the largest contiguous dark-sky-protected areas on the continent.
What you can see in the sky
A Milky Way core so bright it casts shadows, plus zodiacal light and the same skies that make neighboring Big Bend National Park famous for having the least measured light pollution of any lower-48 park unit.
Best time of year
Fall through spring, around new moon — summer daytime heat is extreme even if nights are clear.
