A swimming area is typically marked by a designated buoy, often referred to as a "swim buoy" or "swimming marker." These buoys are usually brightly colored, often in orange or yellow, to enhance visibility and indicate safe zones for swimmers. They help delineate the boundaries of the swimming area, separating it from boating or other water activities. Additionally, swim buoys may have safety information or guidelines for swimmers.
