Pitch a tent in one of three campgrounds or enjoy a solid roof in one of the six hotels ranging from no-frill motels to luxurious lodges. Xanterra operates all park lodges, as well as Trailer Village. Reservations are accepted up to 13 months in advance and should be made as early as possible. For same-day bookings call the South Rim Switchboard. Children under 16 stay free, but cribs and cots are $10 per day.
