Domestic pets are permitted in designated day-use areas at all Florida state parks. They must be kept on a hand-held leash that is six feet or shorter and be well-behaved at all times. Pet owners are required to pick up after their pets and properly dispose of their droppings. Pets are not permitted on beaches or playgrounds, or in bathing areas, cabins, park buildings or concession facilities. Individual parks may have specific areas prohibiting pets.
