Hi. If I arrive at the park at around 3pm on a nice summer weekend day, is it likely I would still find parking? Does the park close at a certain time, and will I need to leave then? Is there a cost for the parking? Thanks so much.

It seem to have been plenty of space my last four beach outtings,

How many cars are you planing to bring?

Yes. , there is plenty of parking

I would advise you not to torture yourself like that, though you just might get lucky!

If you come there around 3:00 p.m. you will wait till about 7:00 p.m. to park

There is a cost to the parking, and it varries on what vehicle you are using. Around 3pm there may or may not be space. It simply depends on the day, but you would be testing your luck coming in that late as the line to the parking lot is huge and may fill up the parking space as well.
