You can. You can also reserve camping area. I don't recall seeing grills however.
Definitely, they have a nice picnic area, but you do have to bring everything involved in the barbecuing. They only have tables.
They have pavilions with tables. They reserve them for parties I believe. Just call first and see of you can use them. I have been there twice and they have never been so busy where more than a third of the tables were being used.
I''m not certain.
