Reservations can be made 6 months out. Best to make them then to be sure you get a site. Very popular place! Well worth it. Great place!
Reservation probably months in advance
Definitely make a reservation. I wouldn't show up without one!
The North Rim books up quickly. I booked my spots back December for my May trip. Since the season is short up there, its hard to book a last minute trip.
I believe 6 months in advance
No but that place gets full pretty fast so if i was you i would.
