Welcome to your premier hobby farm and equestrian retreat, beautifully situated in the scenic Black River Valley on the western edge of the Tug Hill Plateau at 5115 State Route 12 in Glenfield, NY. Spanning an impressive 104 versatile acres on both sides of NYS Route 12, this expansive estate—proudly known for its rich agricultural heritage as the former "Hidden Pastures Dairy"—is a turnkey opportunity for homesteaders and livestock enthusiasts. The property boasts exceptional farming infrastructure, anchored by two magnificent large pole barns. The first outbuilding is a highly functional agricultural hub, outfitted with a milking area, flexible stalls ready for horses, or cattle and provides additional enclosed storage for equipment, implements, toys and feedd. The second provides a dedicated indoor riding arena, which easily doubles as a space for expanded livestock handling, training, or indoor equipment storage. The sprawling acreage offers fertile potential for rotational grazing, hay production, and self-sustaining country living. While the property is a working hobby farm dream, it also delivers unparalleled recreational convenience: you are just 15 minutes from the renowned Otter Creek Horse Trails, with immediate and direct access to the extensive Lewis County ATV and snowmobile trail systems right from your pastures. After a long day tending to the farm or riding the trails, retreat to a beautifully updated 4-bedroom, 2-bathroom home designed for modern comfort. The house welcomes you with a classic covered front porch and features a modern kitchen, alongside the ultimate convenience of a first-floor primary en-suite and first-floor laundry. Step out the back to entertain or unwind on the spacious rear deck, complete with an aboveground swimming pool overlooking your fenced in pastures. Rounded out by a 3-car garage for farm vehicles and outdoor toys, this property seamlessly blends robust agricultural capability with year-round outdoor adventure.
