Where Are Waterpark Simulator Save Files Located?
Waterpark Simulator stores each park in a slots folder under LocalLow, with settings.json in the same CayPlay directory. Steam Cloud covers it.
Last updated
CayPlay's builder keeps everything in one LocalLow folder named WaterparkSimulator, with no space between the words. Park saves sit in a slots subfolder, one entry per park, and settings.json lives directly beside them.
The folder name catches people out. Searching Explorer for "Waterpark Simulator" with a space can come up empty, while the real directory has none. Steam Cloud syncs the tree for App ID 3293260, so the same park loads on another machine once sync finishes. Copy the whole CayPlay folder with the game closed for a manual backup.
