Imagine ending your day to the sound of flowing water—not traffic. Walking your own land to a hidden grotto, private waterfall & even unexplored caves—features most will never experience, let alone own.

Tucked beneath a dense canopy of mature trees along the Blanco River, this is not just a home—it’s a one-of-one Hill Country compound where natural beauty & privacy converge in a way that cannot be recreated today. Just minutes from IH-35 & within 30 minutes of Downtown Austin, it offers the rare balance of convenience & complete escape.

Cross the charming entry bridge & the property immediately sets itself apart. This isn’t typical riverfront—this is an immersive setting where the land itself is the luxury.

The main residence (~2,800 sqft) was designed to live in harmony with its surroundings, featuring expansive windows, natural materials & a warm, grounded feel throughout.

The property extends well beyond the main home. A detached casita (~1,400 sqft) with full kitchen & fireplace offers true independent living—ideal for guests or multigenerational use. A separate spa building features a 6-person sauna, full bath, changing area & sleeping loft, fully climate controlled for year-round use.

Outdoor living is where this property becomes unforgettable—multiple gathering areas, direct river access & a setting that feels like a private resort. Steps lead to the riverbank where clear water & peaceful surroundings define the experience.
Private well w/ full-home filtration & reverse osmosis.

There are homes… & there are properties that rarely exist. This is one of them.
