## Overview
Big Bend National Park has the least light pollution of any national park unit in the lower 48 — a fact the sparse population of the surrounding Trans-Pecos desert makes almost inevitable.

An exceptionally dark Milky Way and star field, with essentially no measurable light pollution.

## Highlights
- Least light-polluted national park unit in the lower 48 states

- Cell service is essentially unavailable throughout the park
