The regulations for fire (when we were out there a couple years ago anyways) stated that you cannot have a fire anywhere other than designated campground areas.
When we stayed there, we camped in the Game Lodge Campground. It was one of the few campgrounds that was open year round, and most of them were closed when we were out there mid-april.
There were plenty of people camping in tents and stuff, but we stayed in the little cabins on the grounds, as it was going to be pretty cold at night and had some rain/snow in the forecast.
There were bathrooms and showers there..
