There is only one private island in all of Palm Beach, and it’s now on the market. Dubbed Tarpon Island, the man-made oasis features a renovated estate from the 1930s that now spans 21,406 square feet. It includes 11 bedrooms, 15 full baths, plus seven half, as well as a spa, sauna, salon, wine room, theater, and fitness center. Along with 360-degree views, the exterior offers a 98-foot swimming pool, cold plunge pool, tennis court, and an entertaining terrace with an outdoor kitchen. The best part is it’s accessible by boat and bridge, making it the most secluded spot on Billionaires Row.
