Can you camp overnight on any of the islands off barge canal or end of 40 in Yankee town?

I've seen people camping on the 2 islands just west of the bird creek boat ramp.

I've seen people camping down there.

I don't think you can camp but we spent the night there in our vehicle we never saw anybody

No overnite at the rest area...lock and key. Islands camping not sure..probably park at boat ramp at the end.
