What time does the park close? Are tourists allowed to stay overnight if they are not camping, specifically fishermen, and sight viewers?

This is true. Closes at sunset. Must have permit to camp.

I think it closes between 6- 7 p.m. no you must purchase a camping permit.

No. You must purchase a day pass to enter and no overnights are allowed in the day use areas.

They close at 8 pm and no you can't stay unless you got a camp permit.

8pm and No

Not at the beach. but you could stay in the town of Boedgea Bay. and the park closes for day use at sunset

They close at dark and only if your camping you can stay .you have to purchase a day pass for 7 dollars I think or a camping pass
