Isle Royale National Park is one of the few national parks to close during the winter. The Island is closed November 1 and will reopen on April 16. The closure is due to the extreme winter weather conditions, for the protection of wildlife, and for the safety and protection of visitors. The Park Headquarters for the winter is located in Houghton, Michigan. The summer headquarters is located at Mott Island on Isle Royale National Park.
