Treked down to San Diego County this afternoon to scout a water park I had read about once, but couldn't find hardly any information about. I had never seen it on the site before, so I thought I should share.
It is quite a hidden gem. The park closed down in 2004 and it fairly well-hidden in the lovely hills. The water slides are really well-preserved and safe to walk down which is great fun. Small park, but looks pretty good after ten years of dormancy.
There is a mobile building on the property though that people are working in during the day, so be wary. They did seem to see us and drive by us in their vehicle, but did not make any verbal fuss beyond that.
