Wonjin Playdoci in Bucheon is a family water park used by toddlers through older adults. It has a lazy river, slides, hot spring baths and a spa, and indoor and outdoor water play areas. During peak season, entry is faster when one person does self ticketing at the kiosk while the rest of the group holds the line, and life jackets can only be taken off above 140 cm. For upper elementary students, the rides are centered on younger ages and the range of slides is limited.
