I don t know of any towns along the New Jersey coast don t allow bonfires on the beach. Many beaches don t even legally allow you on the beach after sunset or 10pm.Margate won t allow it and neither will Ventnor.
As far as I know, there is nowhere near where you are that allows beach bonfires. Sorry. You might possibly be allowed to do one up at Island Beach State Park, but that s a long way.
