Swim Clear Water with Family at Mount Sunapee State Park Beach
Why Rent On Lake Sunapee
Lake Sunapee stretches 8.1 miles through western New Hampshire’s rolling hills with a shoreline of approximately 70 miles, eleven islands, and a depth of 105 feet that keeps the water remarkably clear and cool throughout the summer. The lake is surrounded by working farms, conservation land, and the kind of New Hampshire village character that is increasingly hard to find. For families who want an authentic New England lake experience without driving to the far north of the state, Sunapee delivers it beautifully.
Six Boat Ramps and Every Water Activity
Six public boat ramps, including those at Sunapee Harbor and Mount Sunapee State Park, give families easy water access from almost any point on the lake. Kayaking, paddleboarding, swimming, and fishing for salmon, lake trout, and smallmouth bass fill the warmer months reliably. Dinner cruises aboard the MV Sunapee Lake Queen are a consistently popular evening activity for groups who want to see the lake from the water as the sun goes down.
The Fells: A Garden and Estate Worth Your Afternoon
The Fells on the eastern shore is an 83.5-acre estate once belonging to Secretary of State John Milton Hay, featuring sweeping lake views, beautifully maintained formal gardens, and guided tours of the historic house. The fairy village trail at The Fells has become a particular favorite for families with younger children, who find the small woodland installations genuinely enchanting.
John Hay Wildlife Refuge and Pillsbury State Park
The John Hay National Wildlife Refuge adjacent to The Fells offers hiking through diverse woodland and wetland habitats, and Pillsbury State Park to the northwest adds remote ponds and primitive camping for families who want to extend their outdoor programming beyond the lake itself.
A Sunapee Lakehouse Is Worth Finding
A vacation rental on Lake Sunapee gives your family private dock access, lake views, and a full kitchen in one of New Hampshire’s most classically beautiful lake settings. Properties with hot tubs, covered porches, and space for eight to twelve guests are available throughout the Sunapee Harbor area. Come for the sailing, stay for the gardens, and leave genuinely refreshed.
