Round Mountain, TX 78663 (Hays County)
About this property
Deer Abbey presents a rare opportunity to own approximately 44.482 acres of land with coveted Pedernales River frontage in one of the most desirable growth corridors west of Austin. Tucked into the rolling Texas Hill Country, the property offers a compelling balance of privacy, natural beauty, and strategic value, all within reach of Austin, Bee Cave, Lake Travis, and Dripping Springs. This ranch features a diverse landscape with mature native trees, open usable pastureland, and direct river access—a setting increasingly difficult to replicate this close to Austin. Whether envisioned as a private recreational ranch, family retreat, luxury estate, or long-term land hold, the property offers exceptional flexibility. Several premier homesite options provide the potential to build a residence overlooking both the Pedernales River and the planned Mirasol Springs development (buyer to verify status). An existing 1980s home offers immediate usability and can be updated as a main residence, guest house, or retreat. A nearby secondary building includes a sleeping area, bathroom, and garage, offering excellent potential for a workshop, bunk room, or clubhouse. Properties with meaningful water features and proximity to Austin are becoming limited. Deer Abbey allows you to enjoy a private ranch today while holding a strategic piece of Texas land. The property is currently under an agricultural exemption and features usable land perfectly suited for equestrian use, livestock, or recreational pursuits.
