221 Lower Elgin Rd is located in Elgin, Texas, in Bastrop County. Bastrop County sits at the eastern edge of the Texas Hill Country transition zone, blending the Lost Pines forest, an isolated stand of loblolly pines separated from the East Texas Piney Woods by 100 miles, with open ranch land and the growing spillover of the Austin metro.

The Colorado River flows through the county, and the Lost Pines ecosystem creates a uniquely lush landscape unusual for Central Texas. Bastrop State Park preserves thousands of acres of pine forest that survived and recovered from the devastating 2011 wildfires.
