Soak city is a great place to take the kids during the summer. Soak city is a lot smaller than Raging Waters or Wild Rivers, and for some, probably more centrally located. The other two are quite a drive. Soak City is directly across from Knott's Berry Farm. The thing that is great about Soak City is that it is a bit smaller. Some older adults and kids may NOT like that about the park. I think that the smaller area is good for parents because they don't have to worry about their children as much.
There are a lot of HIGH up slides for the older kids. There is a wave pool for everyone with beach chairs right near the water, mimics a beach pretty well. And they have a very cool huge jungle gym type contraption for the smaller kids. This can dump tons of water on people that are passing by.
Again, some may see that going here is not good, because it is small. It is not too expensive for having a great day at a local water park.
