The aquatic ladder has wide, deep treads, arranged like a staircase, with side and upper railings to make it easy to enter or exit the water, even by elderly people, tired individuals, those carrying aquatic equipment, such as SCUBA gear or water skis, and, even, by pets. The ladder is preferably made from aluminum, although it can be made of other materials, such as steel (e.g., stainless or galvanized), fiberglass, plastic, or other composites.
