Full Moon Bay is a secluded cove in the Eastern Lake, located just south of Ba Sing Se. It is the location of a hidden ferry station that refugees from all over the southern portion of the Earth Kingdom come to on their way to Ba Sing Se.[1]
Aang and company almost crossed the bay this way, but decided instead to venture along the Serpent's Pass when a party with whom they were traveling was not allowed to use the ferry. Zuko and Iroh, however, managed to use the ferry to cross the bay. Suki and the Kyoshi Warriors were once members of the security staff of the ferry station.[1]
