The Jjimjilbang Zone is a relaxation area within Ocean World equipped with hot spring and sauna facilities, where you can warm up and recharge after water activities. Even in winter, the warm hot spring water is maintained, allowing you to experience unique healing by feeling the contrast between cold air and hot water in the outdoor spa zone, making it ideal for families to relax comfortably before and after water activities. However, towels are operated on a separate paid rental basis, so it is recommended to bring your own towel in advance, and you will use a prepaid payment system through a wristband key. If you want to safely enjoy water activities with children and finish warmly in the hot springs, using the Jjimjilbang Zone is recommended.
