48992 Sylvan Is, Alexandria Bay, NY 13607

Welcome to Sylvan Island, a rare and beautifully restored retreat in the heart of the Thousand Islands where history, luxury, and waterfront living come together. Completely renovated by respected local architects and builders, this historic island property has been transformed into a turnkey masterpiece, ready for its next owner to enjoy from day one. Just a short boat ride from Alexandria Bay, the island offers exceptional privacy, protected deep-water docking, and breathtaking 360-degree views of the St. Lawrence River, including the shipping channel, passing boats, and spectacular Canadian sunsets. Inside, the home features four bedrooms and four bathrooms, all finished with impeccable attention to detail. Large new windows frame water views from nearly every room, filling the home with natural light and creating a constant connection to the river. Wake to the sound of loons calling and water gently lapping against the granite shoreline. Designed for both entertaining and relaxation, the home offers two spacious living rooms and a stunning open-concept gathering space anchored by a stone fireplace and chef-inspired kitchen. Two screened porches provide distinct outdoor living experiences—one overlooking the channel and the other perfectly positioned for sunset views. After a day on the water, relax in the hot tub, unwind in the sauna, or climb to the charming cupola tower for panoramic views that stretch for miles across the Thousand Islands. The protected harbor and generous docking accommodate multiple boats, while the connecting island provides opportunities for future expansion, recreation, and exploration. Every aspect of the renovation was thoughtfully executed, from the all-new windows to the custom finishes throughout, blending timeless island character with modern comfort and convenience. Whether hosting family and friends, enjoying peaceful mornings on the porch, or gathering around the fireplace after a day on the river, Sylvan Island offers an unforgettable lifestyle. Move-in ready and requiring absolutely nothing, this exceptional property is a rare opportunity to own one of the Thousand Islands' most impressive private island retreats.
