About This Home

18617 Hwy 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 slightly rolling terrain, highlighted by mature Live Oaks and native wildflowers, slopes to a shoreline protected by an engineered concrete bulkhead. Along Highway 29, more than 2,000 feet of brick and metal fencing with four gated entrances provide both security and a distinguished presence. 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. Unrestricted and 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.
