Not allowed to drink at any state parks in public but you may be able to find a way to be inconspicuous
Only at your campsite. Not on the beach or in the public park area. Alcohol Waiver forms can be purchased for the large group picnic areas. https://www.dohenystatebeach.org/park-information/group-picnic-reservations-100-500-people/
What bill wood said . your not even allowed to drink in public . unless at bars or places that sell it.
If you are camping then yes, just no glass containers. As far as the beach and day use and recreation areas, no you can not drink alcohol there
Nobody ever checked us day or night. But of course we only drank at our campsite.
I can confirm from life guards that approached me a few times, no glass pour into plastic cup all they really care about is glass
