Me and the Toddler are here regularly.
Water Park... Check!
Giant Grassy area.... Check!
Giant Mountainous Hill with Monument on Top... Check!
Lots of moderately dangerous Kids play areas for different ages... Check!
Clean Bathrooms... Check!
The concrete accoutrements of the play areas are rather well done. There's some snake and dinosaur shaped play equipment and a slide that goes through their concrete edifice.
There's always tons of people here on weekends and evenings, but the park is huge so it accomodates well. Great for large gatherings of people. Huge ethnic diversity as well (I call this a plus!)
There's also a giant hill that is not for the be-rascaled. It's a decent feat to climb to the top and you get a beautiful view if completed.
The only thing this park lacks is a food and drink vendor (there is water) and one of those giant wheels to spin really fast. Minor complaints. Good for all ages.
Also: since when are wood chips decent playground flooring? They get into everything and cause splinters.
