The world’s largest indoor theme park with a massive covered section and a smaller outdoor Magic Island area on an adjacent lake — a genuine all-weather guaranteed-good-day option. Day admission runs approx 62,000 KRW ($46) for adults and 52,000 KRW ($38) for children ages 3 and up with toddlers under 36 months free. Open daily 9:30am to 10pm with the indoor section staying open in all weather conditions. Height restrictions apply to most thrill rides so best for kids 110cm and taller though the indoor Fantasy Zone has gentler carousel and slow-ride options for younger children. Jamsil subway station (Lines 2 and 8) connects directly to the park’s underground entrance — no parking hassle required.
