I want to host an event but I will be bringing my own food already cooked. Don't need a grill just space will it cost? I already have my card for Westchester parks

Yes. If you want to reserve a space i believe its $75 for the day. Otherwise, its free but its first come first serve if u dont reserve a space

How can I reserve an area!? Is there a link or a webpage!?

I don't know, I only been there one time...

$10 entrance

No but if you want a grill you need to pay $100 and you will need to pay an entrence wich is $10
