The Esplanade Lagoon in Cairns, Australia, is designed with varying depths to accommodate everyone from toddlers to experienced swimmers. The depth ranges from a very shallow "beach entry" on the sandy side to a maximum depth of approximately 1.5 meters (about 5 feet) in the center and far ends. The lagoon is essentially a 4,800-square-meter saltwater swimming pool that mimics the feel of the ocean without the threat of jellyfish (stingers) or crocodiles. It features shallow "paddling" areas for children with small fountains, and the deeper sections are perfect for lap swimming or cooling off. The facility is patrolled by professional lifeguards every day of the year, usually from 6:00 AM to 9:00 PM. Because the lagoon is so shallow and the water is filtered and chlorinated, it is an extremely safe environment for families. It also features underwater benches for those who want to sit and relax while submerged. The lagoon is free to the public and is the focal point of the Cairns city center, offering a safe alternative to the mudflats of the natural harbor during low tide or the dangerous "stinger season" in the open ocean.
