About

Terlingua Ranch is a vast off-grid subdivision in the Chihuahuan Desert of Brewster County, Texas, near Big Bend. Roughly 5,000 property owners hold about 9,500 tracts across nearly 210,000 acres, connected by 1,100 miles of POA-maintained roads. Most lots have no grid electricity, so residents rely on solar, generators, or wind, and water depends on private wells of widely varying depth.
