If so, the Wanneroo Regional Museum wants to hear your stories and see your photos.
The City of Wanneroo will hold a memory-sharing event in the museum on Sunday, April 21, for people to bring photographs, pamphlets, tickets, postcards, souvenirs and films.
These will be recorded by staff and entertainment on the day will include short films of the slides at the former tourist attraction.
Atlantis Marine Park featured a mini seaworld with performing dolphins and water slides and operated from 1981 to 1990.
Anyone who cannot attend on April 21 but wants to contribute can call 9405 5903 or email email@example.com.
