Texas State Parks Bortle Ratings

Texas has numerous state parks scattered north to south and east to west across the state. Some are perfect for stargazing, and others, for the astronomer interested in dark skies, are to be avoided.

The state parks are listed below, followed by a Bortle Scale Rating from one to nine. The scale rates the darkness of the sky based on a given number of celestial objects that can be seen in the sky. The lower the number the darker the skies. The information below came from Texas Parks and Wildlife.

A map to the parks is located here.
