About This Home
Ideal location at the end of the Rattlesnake Island peninsula, this property is protected from the wind and has a u-shape dock with center 6,000 pound boat lift and new canopy. 326 Rattlesnake Island encompasses 225' of waterfront for you to enjoy all day sun, and in the evening watch the moonrise while listening to peaceful lake and it's resident loons. A level front yard provides an inviting setting for lakeside gatherings. The pristine sandy-bottom and beach welcomes swimmers of all ages, while the covered U-shape dock offers protected docking and easy access to deep-water swimming, waterskiing, fishing, and paddleboarding. There is also a raft with a 1,000-lb anchor disc, and a double-blocked mooring capable of securing up to a 12,000 pound boat. The spacious deck provides the perfect place to relax, dine, and enjoy the views. Inside, abundant glass fills the open-concept kitchen, dining, and living areas with natural light. The warm Hickory Hardwood floors and Cathedral ceilings enhance the home's sense of space, and a propane stove supplies warmth on cooler days. The main level features two bedrooms and a full bath. Upstairs, the open loft, currently used as a game room, has flexibility and could easily accommodate additional sleeping space. A separate storage shed keeps outdoor equipment organized and offers the potential for a bunkhouse. Take advantage of the spacious lot which can accommodate a sizable addition offering a southerly exposure and great views. Island trails lead to the summit, where spectacular 360-degree panoramic views span the whole. Just a short boat ride away, Rattlesnake Landing provides association members with two transient docks, a boat ramp, and two private parking areas. A deeded 30-ft. boat slip at nearby Minge Cove is available for an additional purchase price (will not be sold separately before the sale of the home). This exceptional island retreat offers a Lake Winnipesaukee lifestyle to enjoy for generations to come!
