Not as of this date.
Out of state guests who are vaccinated are being admitted now.
It is limited to Californians. I read they will open to out of state visitors on June.
You have to reserve the days of your visit online before going to the park. I assume the website would tell you if out of state visitors are allowed or not.
The way I understand it is you must be a California resident at this time. No exceptions. But it does sound like that could change soon.
