Big Bend Ranch State Park is one of the few International Dark-Sky Association designated parks in the State of Texas and offers visitors excellent outdoor viewing year round . Compadres supports special events for telescope viewing, laser-guided sky orientation, and photography, and how to preserve this rapidly diminishing natural resource in America.

In an extraordinary setting of raw, rugged beauty and solitude are four world-class facilities managed by the Texas Parks and Wildlife Department:

  • Big Bend Ranch State Park
  • Fort Leaton State Historic Site
  • Barton Warnock Environmental Education Center
  • Chinati Mountains State Natural Area

This is the Big Bend Ranch State Park Complex, a vast resource spread over more than 350,000 acres of some of the most remote, ecologically diverse, culturally rich terrain in the United States. 

Compadres del Rancho Grande (CDRG) is the official 501(c)3 non-profit organization working with the Texas Parks and Wildlife Department (TPWD) to promote and sustain this amazing resource.

Our Mission is to provide resources to support and sustain the parks, enhance visitor experiences, and educate the public on the wonders of the parks and the importance of their natural and cultural resources.


We help meet the needs of the Big Bend Ranch State Park Complex through fundraising, volunteering, outreach, and education. We hope that you will join us.
