Appropriately dubbed the New Hampshire Lakes region, this area of the state is home to Lake Winnipesaukee, the sixth largest natural lake in the United States. Stretching 26 mi (42 km) in length, this lake also contains over 250 habitable islands, making it a prime vacation destination. Several towns are found on the shores of Lake Winnipesaukee, including Meredith, Center Harbor, Moultonborough and Wolfeboro, each offering New England charm, unique accommodations and trendy restaurants. Visitors to the area enjoy taking the Winnipesaukee Scenic Railroad, which offers one- and two-hour scenic excursions along the lakeshore between Meredith and Weirs Beach. The Belknap Mill in the city of Laconia is a popular attraction, as it is the oldest unaltered brick textile mill in the United States. The Lakes region also boasts several annual events, including the Sandwich Fair, which takes place in Center Sandwich in October, and the summer-long Great Waters Music Festival in Wolfeboro.
