WaterPlay offers kids a fun and safe way to cool off under fountain jets and falling buckets of water. Located in Zephyr Park at Fourth Street and Fourth Avenue, the 7,000-square-foot sprayground features arches shooting water and soaker cannons. Benches surround the sprayground so parents can watch the action. Children under 17 must be accompanied by an adult. City parks are open from 9 a.m. to dusk.
