The use or possession of alcoholic beverages on federal park lands within Fire Island National Seashore is allowed for anyone age 21 or older, except in historic structures and visitor centers. The restriction on alcohol in these structures may be waived during special events with written permission via a special use permit.
The National Park Service does not prohibit the use or possession of alcoholic beverages in public areas within Fire Island National Seashore. However, where the Seashore boundaries overlap with town boundaries, town ordinances may be enforced by other agencies. The Town of Islip, Town of Brookhaven, and the Villages of Ocean Beach and Saltaire prohibit the possession of open containers or the consumption of alcoholic beverages in places open to the general public, except where licensed or specially permitted.
Marina quiet hours must be respected between 10:00 pm and 6:00 am. Disorderly conduct is not tolerated, and can result in a fine and/or arrest.
