There’s something rare about owning a place that feels completely removed from everything—yet still within reach. Tucked within Oscawana Lake in Putnam Valley sits a true escape: a private island paired with its own dedicated dock parcel along the shoreline, offering a gateway to a different pace of life. This offering includes two tax parcels—62.10-2-6, the island itself, and 62.14-1-35, a separate dock lot that provides your essential access point. They are being conveyed together, inseparable by design, forming an experience that begins at the water’s edge and carries you across to your own secluded retreat. The journey is part of the story. You arrive at your private dock, step into a boat, and within moments, the mainland fades behind you. What replaces it is stillness—water gently moving against the shoreline, the sound of wind through trees, and a sense of ownership that’s increasingly hard to find. This is not just land; it’s separation, privacy, and presence. The island itself offers a natural setting shaped by time and untouched character. It invites simple, meaningful use—day trips, quiet afternoons, fishing at sunrise, or evenings watching the light settle across the lake. Whether you envision a rustic campsite, a gathering place or simply a personal refuge, the value here lies in the experience rather than development intensity. Importantly, this is being offered strictly as a recreational property to be enjoyed as it is. It’s about preserving what makes it special: the water, the isolation, and the freedom to enjoy it on your own terms. Properties like this are increasingly uncommon—especially with dedicated, deeded access included. Without the dock parcel, the island is just a view. With it, it becomes something far more meaningful: a destination you can reach, use, and truly call your own. Together, these two parcels create a singular opportunity—a place where the shoreline is just the beginning, and the real value lies just beyond it.
