The park and playground areas are free. The zoo and the train ride both cost money.
Playground is free but everything else costs a little bit of money. Very affordable though.
You pay a small fee for the Zoo Bergen county resident/non Adult (15 - 61)$4 / $8 Child (3 - 14)$2 / $5 Child under 3 : Free Senior (62 and up)/Disabled$1 /$2 Active Military Free
Not the playground, but there is an admission charge for the zoo and for the train ride and carrusel. There are BBQ grills around the playground area
One more question. Do they have bbq grills available for the public?
No, they don't
Pretty sure just for the zoo portion.
