Do they still accept cars to come in around 4pm?

Our summer hours are in effect: 7 a.m.-8 p.m. For accurate information about Carney Island, visit our parks directory: https://parks.marionfl.org.

I believe at that time they would not charge you and tell you what time you could stay till.

I don't know 😞

I'm not sure, I'm there in the mornings around 10:00
