Yes, but not at every camp site. There are some community/group camp fire areas. Also, when I was there early Feb, 2023 the store had a problem with their wood supplier and had none. You might call and ask if they allow you to bring wood in.

Yes they are, in fireproof containers like solo stoves etc. They do not provide fire pits or rings.

Yes, fire pits at many sites (double check that your particular site is not an exception.) The store also sells wood.

If you have a fire pit at your site, yes.

Yes, as long as there are no seasonal fire restrictions due to very dry weather. The site we were in didn’t have a fire ring but we brought our own firepit and had a nice campfire.
