Most acreage offers land. Very few offer a setting like this. Set along the iconic Devil's Backbone, this 31-acre Hill Country estate delivers privacy, scale, and expansive country views in a highly sought-after location between Austin and San Antonio. The property unfolds as a true compound with a 5,043 sq ft main residence and 1,650 sq ft guest house, totaling approximately 6,693 sq ft with 6-7 bedrooms, designed for hosting, extended stays, and intentional separation of space. Timeless Texas stone architecture defines the main residence, with vaulted and beamed ceilings, dramatic stone walls, and multiple fireplaces that create warmth and character throughout. The chef's kitchen is built for real entertaining, featuring dual dishwashers, dual ovens, multiple refrigerators, and a generously sized dining area. The primary suite offers a private retreat with a fireplace and peaceful views across the surrounding countryside. What truly sets this property apart is the land itself. Outdoor amenities include a resort-style pool and spa, covered outdoor kitchen, tennis court, pond, greenhouse, aviary, and a mile-long private walking trail that winds the acreage and leads to a natural five-room cave recorded with the Texas Spelunking Society-a rare and irreplaceable feature. A large barn that with little modifications would be suitable for equestrian or ranch use. With a full-house generator, new well pump, septic, and sprinkler systems, this is acreage ownership with confidence. A distinctive Hill Country estate offering land, privacy, and experiences that cannot be replicated.
