About this home

This charming retreat on Rattlesnake Island offers 145 feet of private waterfront on the shores of Lake Winnipesaukee. With a warm southwest exposure, the property enjoys all-day sun, breathtaking sunsets over the lake, and sweeping mountain views stretching from north to south. Designed for making the most of lakeside living, the property features exceptional outdoor space, including a massive deck at the camp and level seating areas along the waterfront—perfect for relaxing, entertaining, or simply enjoying the peaceful setting. Inside, the main camp offers a generous sized primary bedroom, a sleeping loft, an updated kitchen, and an open-concept living and dining area highlighted by sliders and a wall of windows that capture the views and open to the expansive deck. A separate private bunkhouse serves as a second bedroom, providing comfortable accommodations for family and guests. Conveniently located just minutes from Rattlesnake Landing on the mainland, owners enjoy access to two transient docks, a boat ramp, and parking for members with four passes. Start making memories at the lake this summer. (the property had a new 3 bedroom septic installed in 2018).

A great opportunity! This camp has been completely renovated, top to bottom, inside and out. The end result of the owner's quality craftsmanship and creative design is a neat island camp with an abundance of character. A post and beam design with open concept living, dining and kitchen area. You'll find Douglas Fir and a new kitchen complete with stainless appliances. A wall of glass across the front to enjoy the view and bring the outside in! The camp has one bedroom with an open loft and three-quarter bath. The wrap around deck, includes a spacious 20' x 24' deck for grilling, dining, entertaining or hanging out with a good book. Attached by a set of stairs is a private bunkhouse, and nice level area closer to the shore. 145' of Lake Winnipesaukee waterfront on Rattlesnake Island with a magnificent southwestern mountain view and nightly sunsets from the 6' x 30' deep water docking! Time to be on island time!
