Number of Reservable Sites refers to the number of sites within a camp or zone that are reservable relative to the total number of sites that camp contains. for example, 3/5 means a camp has 5 sites, and 3 are reservable. Capacity of each site varies.
Maximum Camper Capacity for Reservations refers to the largest number of people that can reserve that camp. It does not indicate the total capacity of the camp, as some sites may be held for walk-up permits. Note that larger groups may require more than 1 site, and it may not be possible to increase your party size after your reservation is confirmed. Camp sizes vary throughout the park.
