Can you have a small camp fire within your camping site. And can you put a tent up within your rv camping site

Yes there is a fire ring at each camp site. You can speak to the owner about tents in the camper site if it is for additional persons to stay he normally charges ten dollars a day unless it was for children.

As far as I know yes
