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 expansive breakwater provides protection from prevailing winds, along with docking for two boats, and leads to a gorgeous sandy swimming area with custom steps into crystal-clear water. The property also offers direct access to the island’s interior trail system right from your back door. As a member of the Rattlesnake Island community, you’ll enjoy shared ownership of a mainland parcel that includes four parking spaces per lot, transient docking for loading and unloading, and a convenient boat ramp. Start making lasting memories on the lake this summer.
