Ocean World in Hongcheon is a large water park with a wave pool, a lazy river, and water play facilities for children. Visitors move between indoor and outdoor areas to use three kinds of lazy rivers and the wave pool. Without a pass such as the Ocean Pass, waits for popular rides run from one to two hours, and visitors charge a wristband at the kiosk at the entrance. On weekends and during Seongsu, lines are long, and the older facilities and the food at the restaurants are lacking.
