Atlantic Beach is a seaside community on the south shore of Long Island. Located just 21 miles from Manhattan, the sandy beaches in the area are dog-friendly from October through March. Pet owners are reminded to keep their pooches on a leash under 6 feet while they are visiting and that dogs are prohibited from using the boardwalk year round. Although dog licenses are issued by the county, they are rarely checked and this rule isn't often enforced. Responsible pet owners are reminded that dog poop is a pollutant in the waterways, so pooper scoopers should be packed before any trip to the beach.
