Description

A rare opportunity to own property on Big Barndoor Island, Lake Winnipesaukee. One of the last developed islands on the lake, Big Barndoor sits on the southern shore and is only a five-minute boat ride from the picturesque town of Wolfeboro, the oldest summer resort in America. This property enjoys a southwesterly exposure with docking for three boats, sandy swimming, and a lakeside deck. The cottage sits just 30 feet from the water and features an expansive deck across the entire front. With both the sliders and an open layout, the kitchen, dining, and living areas take in incredible mountain views. The primary bedroom offers a half bath and sliders out to the deck. Two additional bedrooms and a full bath complete the convenient one-floor living. Inside Big Barndoor Island, 18 acres of common area and a spacious trail encircle the island—perfect for walking, running, exploring, or walking the dog. This cottage is in a prime location with abundant privacy all around. Settle into one of the many areas to sit and relax, and be mesmerized by the views and impressive sunsets.
