How do I go abt reserving a specific date to have a family reunion at this Park?

You have make the arrangements with the office and I think that you need a Nassau County Leisure pass as well.

You have to call the Wantagh Park itself. As far as I know this is still the number 785-7777. If this isn't the number you can always call information

I'm sure you could find a phone number for Wantagh park if you did a search on Google. Then you can make your apt over the phone.

There's an office in the middle that you can go speak with someone and pick the date and spot.
