Welcome to 46619 Tennis Island, an extraordinary waterfront residence offering commanding views of iconic Boldt Castle along the storied Millionaire’s Row. This 3-bedroom, 2.5-bath home with a 2-car garage presents a rare opportunity to enjoy an elevated riverfront lifestyle in one of the region’s most memorable settings, with a layout designed for both effortless living and easy maintenance. Boating enthusiasts will appreciate 80 feet of docking space, including a 40-foot dock with a deep-water slip ideally suited for a cruiser. The dock has been thoughtfully refaced with new boards and structure, while the expansive deck has been reimagined as a low-maintenance outdoor retreat complete with a propane firepit—an extraordinary setting for relaxing, entertaining, and enjoying views of Boldt Castle. From this remarkable vantage point, you can also watch ships pass by the castle, including impressive tankers and cruise ships, adding yet another layer to the ever-changing waterfront panorama. This exceptional setting also offers what may be the finest view for July 4th fireworks, creating an unforgettable backdrop for summer evenings on the water. Inside, the home is perfectly positioned to capture its spectacular surroundings. From the main living spaces to the private bedrooms, the ever-changing views of Boldt Castle create a striking backdrop that brings a sense of grandeur and tranquility to everyday life. Set within a golf cart–friendly community, the home is just moments from the TI Club for dining, cocktails, and summer treats, with nearby golf adding to the appeal of this coveted destination. Properties with views of this caliber seldom become available, offering the next owner an exceptional chance to personalize a premier waterfront address.
