About 18617 E State Highway 29

Introducing The Lighthouse on Lake Buchanan — a rare waterfront property encompassing ±23 acres with over 3,600 feet of open-water frontage on the southern end of Lake Buchanan, the largest lake in the Highland Lakes chain. Anchored by its iconic red-and-white lighthouse, the property offers expansive panoramic views of both the lake and the Texas Hill Country. The gently rolling terrain, highlighted by heritage Live Oaks and native wildflower meadows, slopes to the shoreline, which is reinforced by an engineered concrete bulkhead. Along State Highway 29, more than 2,000 feet of brick and metal fencing with four gated entries provide both visibility and security. Improvements include 12 bungalows with stone exteriors and metal roofs, as well as a central clubhouse with two bedrooms, a full kitchen, and a covered patio overlooking the pool and lake. Additional structures include a pool house, two conference buildings, a fixed pier with dock, four concrete boat ramps, multiple water entry points, a designated cove for kayaking, and a sandy beach. Supporting features consist of a commercial-grade laundry facility and several storage buildings. Municipal water and electric utilities are in place. Adjacent to LCRA’s dam operations, The Lighthouse on Lake Buchanan offers ultimate seclusion yet convenient access from Austin and the Texas Hill Country — a true hidden gem with limitless potential. With its size, location, and extensive improvements, the property is well suited for a range of uses including a corporate retreat, family compound, luxury campground, RV resort, event venue, marina, winery, or long-term investment. Located at Lake Buchanan’s south end along Highway 29, it’s 1 hour 15 minutes from Austin, 1 hour from Lakeway, 45 minutes from Leander/Cedar Park, and 15 minutes from Burnet airport. Nearby amenities include Spider Mountain bike park, Torr Na Lochs winery, restaurants, HEB stores, and Marble Falls’ breweries and festivals (25 minutes)
