Library Avenue, Charlie Gregorini Memorial Park, Ellenbrook, WA
Rainbow Waters, also called the Ellenbrook Water Playground, is part of Charlie Gregorini Memorial Park on Library Avenue. The City of Swan runs it from late September to May, 9am to 7pm each day, with fountains, bubble jets and spray guns for children to aim at each other. Barbecues, picnic tables, shaded spots and toilets are in the park, and there is car parking nearby, which makes it workable for a long afternoon.
In Ellenbrook, Rainbow Waters Playground is one of Perth's largest water playgrounds, with fountains, bubble jets and spray guns.
