About this home

Rustic seasonal waterfront camp on Rattlesnake Island with 210 feet of shoreline on a spectacular point setting. Enjoy dramatic 180-degree views looking west to Gunstock Mountain and north toward Meredith, with crystal-clear water and stunning sunsets. The shoreline is naturally protected from northerly winds, and the dock is tucked in a sheltered cove for easy access. This island retreat features 3 bedrooms, and one ¾ bath, plus a loft with its own ½ bath. The original front portion of the camp was built in 1965, with an addition and a 3-bedroom septic completed in the early 1990s. Inside, wide plank wood floors, shiplap pine walls, and ceilings create a warm, rustic feel, accented by a stone hearth with woodstove. Two large decks provide inviting outdoor living spaces, perfect for entertaining, relaxing, or taking in the natural surroundings. A large shed offers convenient storage for tools and water toys. Nestled among the trees, this property combines privacy, charm, and the beauty of Lake Winnipesaukee, offering an ideal setting for seasonal island living.
