The center area of the lake is called The Broads.: 31 The lake contains at least 264 islands, half of which are less than a quarter-acre in size, and is indented by several peninsulas, yielding a total shoreline of approximately 288 miles (463 km). The driving distance around the lake is 63 miles (101 km). It is 504 feet (154 m) above sea level. Winnipesaukee is the third-largest lake in New England after Lake Champlain and Moosehead Lake.

The crew of the RMS Titanic were among the estimated 2,208 people who sailed on the maiden voyage of the second of the White Star Line's Olympic class ocean sea liners, from Southampton, England to New York City in the United States. Halfway through the voyage, the ship struck an iceberg and sank in the early morning of 15 April 1912, resulting in the deaths of over 1,500 people, including approximately 688 crew members.

The Lakes Region of New Hampshire is located in the east-central part of the state, south of the White Mountains Region and extending to the Maine border. It is named for the numerous lakes in the region, the largest of which are Lake Winnipesaukee, Lake Winnisquam, Squam Lake, and Newfound Lake. The area comprises all of Belknap County, the southern portion of Carroll County, the eastern portion of Grafton County, and the northern portions of Strafford County and Merrimack County. The largest municipality is the city of Laconia. Besides the lakes, there are also two small mountain ranges, the Belknap Mountains which lie to the southwest, and the Ossipee Mountains to the northeast. The area is a popular tourist destination in the summer time, with the activity peaking during the annual Motorcycle Week and races at Loudon's New Hampshire Motor Speedway. Other tourist destinations include Funspot in Weirs Beach, the Squam Lakes Natural Science Center in Holderness, the children's museum of Center Harbor, Gunstock ski resort and Bank of New Hampshire Pavilion at Meadowbrook, both in Gilford, Castle in the Clouds in Moultonborough, and the town of Wolfeboro, which claims to be the nation's oldest resort town. Lake Winnipesaukee is the largest lake in the state, and is home to numerous vacation homes. Several motion pictures have either been filmed or set in the region, including the 1981 classic, On Golden Pond (filmed on Squam Lake in the town of Holderness) and the 1991 comedy What About Bob?, which was filmed in Virginia but (fictitiously) took place in Wolfeboro.
