This remarkable 97-acre Hudson River island represents one of the most significant waterfront opportunities in the region. Elevated and naturally pristine, the property features more than a mile of riverfront and sits adjacent to 72 acres of state-protected land, offering a vast landscape of unmatched privacy. Positioned as a rare blank canvas on an iconic American heritage river, it is suited for a private legacy estate, a secluded retreat, or a visionary income-producing venture.
Property Details
The island’s topography is exceptional, rising to an elevation of over 145 feet above sea level. These elevated lands are protected by berms and situated entirely outside the 100- and 500-year floodplains, providing a secure and stable environment for future construction. A broad plateau offers an ideal building site with sweeping southern views across the Hudson Valley. Unique to this listing are rare 19th-century underwater rights that extend beneath the river and an adjacent tributary, adding significant long-term proprietary value.
Land and Water
The terrain is a diverse mix of lush forests, open plateaus, and sandy coves. The extensive shoreline includes beach areas that accommodate a wide range of watercraft, including motorboats, jet skis, and houseboats. Recreational utility is further enhanced by an already approved multi-phase dock permit, allowing for immediate water access development. The island's specific geography creates a distinct micro-climate, with summer temperatures and foliage arriving three weeks earlier and lingering three weeks later than the surrounding mainland.
Access and Utilities
While offering profound seclusion, the island remains minutes from the historic village of Castleton-on-Hudson, a major train station, and the state capital. Access is versatile, supporting arrival by water, air, or foot, with an emergency road in place for limited vehicle use. Directly across the river, a town park and kayak launch provide convenient secondary access and mainland connectivity.
Lifestyle and Value
This island offers a "million miles away" atmosphere within the heart of the Hudson Valley. The combination of significant acreage, approved maritime permits, and its proximity to urban conveniences makes it a singular asset. Whether developed for private family use, outdoor adventure, or as a conservation-minded legacy project, the property stands as an extraordinary and irreplaceable natural resource.
