Negative on the water slides, but worth the trip anyway
No water slides in the Park, but plenty of picnic areas and opportunities to cool off along the way.
There's an entire water recreation area on the way in to Three Rivers. We stopped and cooled off on our way home. it was free at the time but it looks like they do charge for entry at sometimes of the year.
Not sure what do you mean by water slides, but there is a great call and lots of picnic spots on Kings river
