There are sites with electric and they cost most and then you can make reservations those are next the last is walk-in you pay then. I stayed 2 nights reserved no electricity and at Buck horn campground it was 32$ for both nights the bath n showers were best I've been to in a long time. Highly recommend. The swimming at Little Niagara close by is free and also lake is free they do have little barbecue set ups with benches and table near both free
I've never asked I can't help you on that one I'm sorry
Think it varies 6 to ,10
