PORTER, Ind. -- With Indiana Dunes National Park being a popular spot for boaters, rules for boaters are being enforced for the safety of boaters and swimmers alike. All waters within 300 feet of the shoreline are subject to national park rules.

Boat operators must have at least one US Coast Guard approved floatation device for each passenger. In addition, they cannot operate a boat while under the influence of drugs and alcohol.

Operating a vessel within 500 feet of a designated swimming beach, within 100 feet of a diver's flag unless for support, and while a passenger is riding while not secure and in an unsafe position is prohibited. These rules are enforced national park rangers patrolling Lake Michigan via boat.

Personal watercrafts, such as jet-skis are not allowed. For more details, see here.

Boaters entering the park water for recreation need a national park pass. For details about the price and types of passes that are available, including free passes for veterans, Military Gold Star families, people with disabilities, and more. See here.
