designated 80 percent of the land area () of the national lakeshore as the Gaylord Nelson Wilderness on December 8, 2004. (Public Law 108-447, Division E, Section 140.) Of the twenty-two Apostle Islands, the wilderness area fully or partially covers eighteen and preserves the prohibition of motorized travel on the wilderness islands. It is the largest wilderness area in Wisconsin. It is named for Gaylord Nelson, a U.S. Senator and governor of Wisconsin, who was instrumental in establishing the National Trails System, the Wilderness Act, and Earth Day. The National Park Travelers Club held its 2012 convention at the Apostle Islands. Recreation Many of the islands offer public docking; a small fee is charged for overnight use. The shoreline contains some historical sites, such as the many lighthouses throughout the islands. Fishing on Lake Superior is a popular activity for both boaters and non-boaters. The lake holds several species of trout and some species of salmon. In seasons when the water is warmer visitors can catch fish from the shore in water as shallow as ten feet. Camping options range from more civilized sites that offer many amenities, such as well water, vault toilets, and food lockers, to sites that are more remote, further from other campers and offer nothing more than a tent pad or fire ring. Camping is offered on 18 of the 21 islands in the national lakeshore. Permits are required from the National Park Service in advance; reservations for group sites begin most years in January and for individual sites 30 days in advance. Hunting is permitted on some islands for certain periods of the year. Game include white-tail deer, black bear, grouse, and other small game. As white-tailed deer have become abundant in recent years, deer hunting opportunities have been plentiful, although the logistics of hunting on the islands can be difficult. Hunting black bears is limited to two islands, and there are rules and regulations that apply only to specific areas. To get from island to island many visitors choose to kayak, either bringing their own kayaks and equipment or renting from a local shop. The islands also offer opportunities to scuba divers to view interesting rock formations and shipwrecks. Scuba diving within a quarter-mile of any island shore requires obtaining a free permit from the park's visitor center.
