What's the best days to go

I agree with the others everyday is good they have a lot to do and the park is very big but the best thing about Cerritos and it Park's there are many to choose from and thanks to some good planning every neighborhood has a park thank you Cerritos

Any day is good, as long has you enjoy your walk or run. Early morning is the best.

They're all pretty good, it's never really too busy any time I've gone.

Any day is great plus the pool is open

Any day is good
