About This Home
Spectacular 180-degree views from north to south await at this meticulously maintained property on Rattlesnake Island, set along the shores of Lake Winnipesaukee. This three bedroom, open-concept, post-and-beam cottage features beautiful pine floors and is filled with natural light from a wall of sliders that seamlessly brings the outdoors in. Step outside to enjoy two spacious decks, one perfectly positioned for sun, the other offering a shaded retreat.

The property also offers direct access to the island's interior trail system right from your back door.

Start making lasting memories on the lake this summer.
