Yes, you should stop.....

If you're traveling on the River Road near Big Bend, there's a place you really need to stop and explore:  Barton Warnock Environmental Education Center.  The humble little building serves as the eastern entrance to Big Bend Ranch State Park and is a regional information center. It is there to introduce the Big Bend area to the traveler and to encourage the preservation of the diverse natural and cultural resources, including adjacent areas in Mexico. The center has interpretive exhibits, a biological gallery, photo exhibit, library, regional artifacts, desert gardens and picnic areas.
