The park is closed to camping; open for day use. There are forest service and private campgrounds nearby. It would be a good idea to check ahead of time.
the camp grounds are closed right now because of virus. If taking a road trip, I highly recommend calling ahead to several places to check their status.
You can camp at lake siskiyou or castle lake. I camped at gumboot campground since most were taken and gumboot lake is quite nice. You can also get a hotel at mount Shasta town.
There are hotels in the town of Burney. I heard Federal campgrounds in the area are still open but I would definitely check that out before you leave
