Enjoy the largest lake in the United States! Lake Winnipeasaukee covers 72 sq miles of the Lakes Region. Head to Alton Bay (address below) and enjoy the Mt. Washington cruise around the Lake, or rent a kayak and enjoy the lake on your own. There you can pick up a map of the lake and take on Weirs Beach, Meredith, or Wolfeboro. There is so much to do along the lake!
