## Overview
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 to see
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.

## Highlights
- Gold-tier IDA designation — the highest dark-sky rating a park can earn
- Adjoins Big Bend National Park to form one of the largest dark-sky-protected regions in North America
- Remote enough that there's effectively no light dome in any direction

## Tips
- This is genuinely remote — fuel up and carry extra water before you drive in
- Roads are mostly unpaved backcountry; a high-clearance vehicle helps
- Cell service is essentially nonexistent — download maps in advance
