Van Saun Park in Paramus is awesome, though right now, part of the playground is under construction, and I don't like the fact that it is not enclosed - not a big deal if your kids are older, but not good for toddlers like mine. The Lyndhurst Town Park is awesome too - big playground AND a sprayground which is free and open to everyone. If you don't know what a sprayground is, it's got fountains where water comes out of the ground and over your head, and in hoop tunnels, etc. Basically a water park with no slides or pools. Good for all ages, even babies.
