I have looked at the site map and I don't see any spots for where grills would be. Are grills available or do you need to bring your own at the tent site?

Some of the sites do have grills, some of them do not. I'm in the same boat as Kelli who answered before me, we bring our own grill and don't run into any problems this way. But I do know with certainty that I have seen free-standing charcoal grills on some of the sites.

We have always brought our own. I do not remember seeing any at sites or an area for them.
