You only HAVE to pay admission... The lodge at North Rim is spectacular! They have rooms/cabins to rent. Restaurant is there as well. It's beautiful there!!
The only payment is the admission from what I know.
Book only the hotel! Because already in spring it will be super crowded. For the rest, go and pay the entry ticket once you are there! (€ 35 car) .. Enjoy!
