WHERE NATURE IS YOUR NEIGHBOR Steeped in Texas history, Serene Hills was once home to natives who roamed the wild limestone countryside. As time passed, the land later became the location of a Texas cattle ranch run by the local Heard family. Now a residential community, Serene Hills is committed to preserving the area's historical value. In order to protect the hills, we encourage the conservation of native Texas wildlife by providing a space reserved for nature and its inhabitants. Of the 456 total acres in Serene Hills, only 114 are open to development. Luxury custom homes starting at $550,000 are surrounded by 342 acres of undeveloped reserved land with scenic hike and bike trails.
