Do I need to make a reservation?
Not unless you have a party of 25+. Otherwise, fire rings at both beaches are first come, first serve.
And if you do find yourself with a party of 26 or more, 1) wow you have a lot of friends, and 2) it’ll cost you $50.
What can I burn?
Both beaches are BYOFW (bring your own firewood), untreated and unpainted. Also, you CAN'T burn:
-Any wood with nails, hardware, or paint
-Scavenged wood or kindling from the surrounding beach/park
-Accelerants, like lighter fluid
