A private island on the Hudson River, just 70 miles from Manhattan. Accessed by a gated entry and private footbridge, this exceptional estate offers complete privacy, panoramic water views, and a rare sense of separation from the everyday. The main residence is designed to embrace its natural surroundings, with walls of glass and every principal room oriented toward the river, capturing light, movement, and breathtaking sunsets. Indoor and outdoor living flow seamlessly to multiple terraces overlooking the water. A true compound, the property includes a detached guest suite, media and game spaces, and an outdoor kitchen pavilion designed for effortless entertaining. A striking observation tower provides elevated 360-degree views and serves as a defining architectural focal point. Curated landscaping, stone pathways, and intimate outdoor spaces create a setting that is both refined and deeply connected to nature. Previously offered privately, this rare Hudson River island retreat is now selectively introduced to the market. Shown by appointment to qualified buyers.
