Does it cost to go to this beach currently?

Belmar beach is $10 per person, under 13 is free. (Before 6 pm) And you pay online no cash.

Yes it's $6, kids are free under 13 yrs of age. But after 6pm it's free to enter

I also was able to pay at beach, they have cashiers at certain locations

Yes

Thank you i thought all new jersey beaches were free this year

Yes however lifeguards are gone I believe at 4:00 P.M.
