Well it's not exactly a fire pit, but they do have a little grill there for cooking. You can only use charcoal, no wood burning. I don't think they have objections to your own grill, but I know you can't just build a campfire on the ground.
Ohh and don't forget to bring a hose. The spicket is split into two, one for your water hook-up, and the other has a hose on it for emergencies (like your grill getting out of control).
Now if you want to sit around a toasty fire, they do the movie at night with two fire pits for making smores. Which btw, is ten times cheaper if you buy the stuff before going.
Are you gonna be staying at the preferred site, full-hook up, or partial hook up??
We stayed at the preferred site with our dog, in the 300 loop. Which was really nice. Even though we were there with our itty bitty two person kiddie pop up tent. One of about 3 people there in the middle of the summer with only a tent out of all the campsites. There was even a guy there that drove a motorcycle, that had a one person pop up camper on the back. I felt so "sheepish" there.
