Spend a fun-filled day with the whole family at Vivaldi Park Ocean World. Relax in complimentary transportation from central Seoul, then hop in a canoe for a 1-hour ride along the Hongcheon River. Afterwards, it’s time to get wet. Enjoy unlimited access to the park’s water rides, including a mega slide zone, surfing mount, and extreme river. If slides aren't your thing, unwind at the onsite jjimjilbang (Korean spa).
