Weirs Beach is an area within the northern part of the city of Laconia in Belknap County, New Hampshire, United States. It is located on the southern shore of Lake Winnipesaukee. The cruise ship Mount Washington terminates there. It is a popular destination of bikers during Motorcycle Week every June.
Weirs Beach, or "The Weirs" as it is referred to by locals, is named for a wide, sandy, public beach on Lake Winnipesaukee. Adjacent to the beach and comprising the center of the village are a boulevard and boardwalk that run along a quarter mile stretch of Lakeside Ave. The main summer port of the Winnipesaukee Flagship Company's MS Mount Washington is located on the boulevard. A large public dock is also evident at this popular stop for boaters on Lake Winnipesaukee. On the opposite side of the street are several seasonal arcades and vendors that have been located there for many years. The Winnipesaukee Pier juts out into the lake from the main boulevard. The pier was constructed in 1925 and was a bustling spot for many years attracting many of the most famous big band groups of the time.
The Weirs Beach area also contains a drive-in movie theater, the Winnipesaukee Playhouse, Funspot Family Fun Center, Mount Washington Cruises, the Winnipesaukee Scenic Railroad, Half Moon Amusement Arcades, and several motels and cottage complexes. Condominiums abound, and there are three marinas offering new and used boats, parts and accessories, dockspace, storage, and rental boats for outings on the "Big Lake".
