Property Description
Set along the Merrymeeting River in the heart of Alton Bay, this three-bedroom, two-bath waterfront home offers approximately 1,900 square feet of living space plus a bonus room, with direct boating access to Lake Winnipesaukee once you pass beneath the Merrymeeting River Bridge. Inside, the layout is bright and open, with water views from the main living areas and flexible space that suits full-time residents, second-home owners, or those exploring a Lakes Region rental. The bonus room adds useful square footage for a home office, den, or guest overflow. The waterfront setup is the standout feature. A private boathouse and dock sit right at the river's edge, and a detached garage handles storage for a boat trailer, kayaks, paddleboards, and seasonal gear. Cast off from your own slip and reach the big lake within minutes. Location is another draw. Downtown Alton Bay's shops, restaurants, public beach, bandstand, and summer events sit just up the road, giving this address the feel of a village neighborhood with true Winnipesaukee access. The area stays active through the warm months and settles into a quiet lakeside rhythm off-season. A Merrymeeting River waterfront with a boathouse, dock, garage, and boat access to Lake Winnipesaukee, all within walking range of downtown Alton Bay.
