Do the non primitive tent camping site have fire rings? Are you allowed to have camp fires?

Yes and yes

Nothing like sitting next to a camp fire there. We do all our cooking on the camp fire. They do have times during the year due to drought when there are fire bans but the Rangers will let you know. Enjoy! Great park.

Yes you are allowed, the rings are already there. They also sell firewood at the park as you go towards the bathhouse. Enjoy! It's a beautiful, peaceful park.
