About this home

The long range 180 degree lake and mountain views are MESMERIZING from this Post and Beam Home located on Rattlesnake Island, Lake Winnipesaukee. These are some of the best views the lake has to offer. Lakeside at the property you will find crystal clear water, a sandy bottom for swimming, spectacular sunsets, and a u-shape dock with breakwater, offering plenty of space for up to three plus boats. The entire length of the house has an oversized multi-tiered deck that is perfect for grilling, outdoor dining or just relaxing. Inside you will find plentiful natural sunlight and large floor to ceiling windows offering views from every angle of the open concept great room. Two large bedrooms and a spacious sleeping loft, provide that extra room for friends and family. The home has a three-quarter bath, as well as a large outdoor shower. A stroll out back will take you to oversized shed/workshop which could easily be renovated into a bunkhouse. This property also abuts the interior access road which makes it easy for any future renovations of the home. The road is a direct link to the trail system on the island that leads up to the very top, where you can see the entire lake and mountain ranges. The Rattlesnake Association also has the benefit of a mainland property providing 4 parking spots to each member, as well as a boat ramp and docks for loading and unloading. This property has all you need to start enjoying lake and island living.
