About the Venue

Alligator's Creek Aquatic Center is a full outdoor water-play destination inside Civic Park with enough variety to work for mixed-age families. The splash pad and interactive water playground give younger kids a gentler place to play, while older kids can rotate to slides, the floating bridge, lazy river, and lap-pool features. This is a stronger fit for families planning a longer half-day outing than a quick free splash stop, and it works especially well when you want something that still includes shallow-entry and all-abilities splash options.
