580 Oscawana Lake Road Putnam Valley, NY 10579

Set on nearly 60 acres of extraordinary land in Putnam Valley, this is a rare and remarkable opportunity to own a private estate of true scale—where natural beauty, serenity, and possibility converge. Backing directly to Fahnestock State Park, the property enjoys permanently protected surroundings, creating an uninterrupted backdrop of forest, sky, and seasonal color.
From the moment you arrive, the setting is captivating. A long, private driveway leads you through a landscape rich with mature trees, thoughtfully tended gardens, and open, sun-dappled clearings. The grounds are simply stunning—offering a level of privacy and tranquility that is increasingly rare. Explore your own 1.5–2 mile walking trail, take in the sweeping views from the higher elevations, or reimagine the charming pond—once used for winter skating—as a centerpiece of outdoor living once again.
Built and meticulously maintained by its original owner, the nearly 3,900-square-foot Colonial home is perfectly positioned within this idyllic setting. A dramatic two-story entry welcomes you, with formal living and dining rooms on either side, both flowing effortlessly into the heart of the home. The family room, anchored by a wood-burning fireplace, opens to a spacious kitchen with granite countertops—ideal for everyday living and entertaining alike.
Step outside to the expansive screened-in porch, where meals, morning coffee, and quiet evenings are elevated by the surrounding beauty and sounds of nature.
The main level also features a powder room, laundry area, garage access, and a secondary staircase leading to a versatile bonus room—perfect for a variety of uses.
Upstairs, four generously sized bedrooms include a truly special primary suite. The recently renovated spa-like bath offers radiant heated floors, a freestanding soaking tub, and a glass-enclosed shower—bringing a luxurious, retreat-like feel—along with two walk-in closets. An additional dedicated office space provides flexibility for today’s work-from-home lifestyle.
Beyond its undeniable beauty, the property also offers compelling future considerations. Previously approved subdivision plans for seven lots have expired, but may present potential for renewal subject to appropriate approvals and due diligence.
Despite its peaceful, estate-like setting, the location is highly convenient—within commuting distance to New York City and close to major highways, shopping, and the scenic Hudson River.
Opportunities like this are exceptionally rare—nearly 60 acres of pristine land, timeless charm, and unmatched privacy in Putnam Valley. A true country retreat with enduring appeal.
