Most splash pads in public parks have no admission fee. Some city-run spray grounds and water parks charge a small fee or require a pass, so check each pad's page.
In California, many outdoor splash pads open in spring (often March to May) and stay open into early fall. Ontario parks set their own dates and hours, and pads shut off during storms.
