Mid-month adds Jarasum Jazz, Icheon's rice festival, pine mushrooms and salmon in Yangyang, and silver grass on Haneul Park in Seoul and on Hwangmaesan. In the second half, the chrysanthemum shows open at Hampyeong and Iksan, Gangneung holds its coffee festival, Wonju fills its old downtown with dumpling stalls, and Busan marks UN Day (24 October) with the UN Peace Festival beside the UN Memorial Cemetery.
