Discover an extraordinary 320+ acre legacy property in Putnam County — a former summer camp steeped in history and now poised for its next chapter with absolute privacy and limitless potential. Spanning 8 separate tax lots, the offering includes nearly 50 acres of commercially zoned land across 3 parcels and approximately 270 acres of residentially zoned land across the remaining 5. The crown jewel is the 95.63-acre flagship parcel, entered from Ballyhack Road, where a pristine 20-acre private lake with a newly updated dam and semi-developed waterfront awaits. Miles of established trails wind through the property, passing dozens of the original camp structures that still stand in various stages of disrepair— a lakefront lodge, large dining halls, recreation and education buildings, dormitories, medical facilities, and even an inground pool — all evoking a bygone era while inviting imaginative reuse or redevelopment. A brand-new, never-used $7 million state-of-the-art sewage treatment plant capable of servicing 60-65 homes sits ready on site, complete with current SPDES permit, full generator, and 100% redundant backup system. An additional entrance can be reclaimed from Old Route 22 via one of the commercial parcels, offering outstanding accessibility and development flexibility. Beyond the private lake, the land is enriched by two tributaries of the East Branch Croton River and approximately 1,640 feet of direct frontage on the river itself — a renowned stretch for kayaking and canoeing within the pristine Great Swamp watershed. At the Ballyhack entrance, a charming 3-bedroom ranch home serves as the ideal caretaker’s residence or gatehouse. Rolling topography, mature woodlands, and dramatic elevations create a landscape that feels worlds away, yet the property remains remarkably convenient to major highways and Metro North train stations for easy access to and from NYC. Surrounded by nature's embrace, every acre beckons for recreation and adventure, defining the perfect escape for those seeking solitude, sport, and serenity. The possibilities for development and use are vast with the permitted and special uses available with this multi-zoned, multiple-parcel property. A sample of permitted uses in C1 zoning include: research and development, veterinary hospitals, greenhouses and nurseries, restaurants, health or fitness clubs, recreational sports facilities, business and professional offices, banks, drive-in and fast food establishments. A sample of special uses include: light manufacturing, retail centers, warehouses, conference and cultural centers, membership club, nursery schools and day care centers. Rarely does a canvas of this scale, privacy, natural beauty, and built-in modern utilities come available. This is more than land — it’s a once-in-a-generation opportunity to shape something truly remarkable.
