There are 2 water "parks" in corona. Citrus park which is a real water park but there's also a TON of people and kids there. I haven't taken them yet cause the thought of them running in 2 directions freaks me out. So that leaves the other. Dos Lago's. Not really a water park but it has a covered playground and a lil splash pad. Plus there's maybe 5 kids there at a time. We've already gone twice and Im sure we will be going at least once a week. The kids love it!
