Bear Island is the second largest of the 258 islands in Lake Winnipesaukee in New Hampshire, United States. In the summer it is accessible only by boat because it is not connected to the mainland via a bridge. In the winter it can be reached by crossing the frozen lake, including snowmobile. According to the Lake Winnipesaukee Historical Society, the island got its name when a few hunters along with a few members of the Pennacook tribe were sent to survey the island. However, they encountered a few bears, which they decided to hunt.
