Full Moon Bay is a small secluded cove on the western side of a large waterway. The port there has a ferry station that takes refugees across the waterway to another port at the outer wall of Ba Sing Se. They then take a train ride from the outer wall to the metropolitan area through the city's farmlands. Full Moon Bay is the fastest and safest way for refugees to get from the western side to Ba Sing Se and it is popular because of it cannot be found by the Fire Nation.
