378 Sleeper Island, Alton, NH 03810

This property sits on the northwest end of Sleeper Island on Lake Winnipesaukee and offers sunsets galore. The quintessential cottage captures everything island living is about—cozy, well cared for, and loaded with waterfront charm. Inside, the open-concept living, dining, and kitchen area features multiple sliders that frame views from every angle. A wood stove provides warmth on chilly evenings and adds ambiance on rainy days. The first-floor primary bedroom has its own access to the full bath, while upstairs a spacious loft offers two private sleeping areas positioned to wake up to island views through a high cathedral window. Walk out the first-floor sliders to one of several multi-tiered decks—perfect for grilling, entertaining, making s’mores, or relaxing with a good book. Down a level, another deck offers direct access to the lake and sandy swimming. From either deck, enjoy long-range views across Lake Winnipesaukee, abundant sunshine, and the most beautiful sunsets. When you’re ready for a break from the waterfront, step out back to the island’s interior trail system, perfect for hiking and spotting wildlife. There’s still plenty of time to enjoy the lake this season and plan your personal touches for next summer.
