Premier Lake Travis Waterfront Estate | 3+ Acres | 400+ Ft Main Basin Shoreline

Positioned on over three private acres with more than 400 feet of shoreline along Lake Travis’ main sailing basin, this gated estate represents a rare combination of scale, usable waterfront, and long-term value—an increasingly scarce offering on the lake.

Expansive windows frame panoramic lake and Hill Country views, filling the home with natural light. Open-concept living and dining spaces extend seamlessly to covered terraces, creating a true indoor-outdoor lifestyle designed for both everyday living and elevated entertaining. Soaring ceilings, a stone fireplace, and refined finishes anchor the main living areas.

The chef’s kitchen is equipped with Thermador appliances, custom cabinetry, and a large central island, opening directly to the living spaces and outdoor areas.

Two main-level primary suites offer private retreats with lake views and spa-inspired baths. An elevator connects to a lower level featuring guest quarters with private entry, a fitness space, and a five-car garage—ideal for extended stays or multi-generational living.

The grounds offer a true Lake Travis compound experience, with mature Live Oaks, rolling lawns, resort-style pool and spa, sand volleyball court, multiple firepits, and a private boat dock with deep-water access.

Located in Travis Landing, residents also enjoy access to a 35+ acre waterfront park with private boat ramp.

A rare opportunity to own a premier waterfront estate combining privacy, scale, and lifestyle in one of Lake Travis’ most desirable settings.

Your basecamp for Lake Travis just hit the market: 15210 Rainbow One Street in Austin, a 6-bedroom waterfront estate on 3.03 acres with 400+ feet of direct shoreline on the main sailing basin. This is where your jet ski sits idle no longer.

The property sits in Hudson Bend's Austin community, one of the few gated waterfront developments on Lake Travis where you can launch straight from your dock. Your commute to Dell's Round Rock campus runs under 30 minutes; Apple Park in Cupertino is a weekend escape instead of a daily grind. Lake Travis ISD schools serve the area, with your children attending Lake Travis Elementary, Hudson Bend Middle, and Lake Travis High.

The home's design centers on immediate water access. A private boat dock sits at the end of your lawn, backed by a five-car garage that stores your gear: kayaks, paddleboards, wakeboard equipment, whatever you're launching that morning. The main level opens completely with cathedral ceilings and a kitchen island that doubles as mission control before you head out. Two primary suites on the main floor let you and a guest recover with lake views. An elevator drops you to the lower level where a home gym, guest quarters, and that oversized garage wait.

Your activity hub spreads across the grounds. The resort-style pool connects to an oversized hot tub for recovery days. A sand volleyball court handles evening tournaments. Multiple firepits define your gathering zones. Mature Texas Live Oaks shade rolling lawn that slopes gently toward the water. This isn't a house that sits empty while you're out living.

Austin itself has a 35+ acre private waterfront park with dedicated boat ramps, meaning zero delays getting on the water. Hill Country views frame the shoreline from every major window. The masonry and stucco construction has held through decades of Austin weather. At $832 per square foot for 8,116 square feet, you're paying for waterfront access with a 400-foot runway, not just views.

This property moves because active buyers understand the equation: no commute friction, immediate water launch, covered storage, and a landscape built for doing rather than admiring. Your next adventure starts at your dock.
