Park Habio Water Kingdom Water Park & Jjimjil Spa

Park Habio Water Kingdom Water Park & Jjimjil Spa is a large indoor water-park-and-jjimjilbang complex in Seoul's Gangdong area, run as a year-round indoor leisure-and-spa destination. The water-park side bundles wave pools, family slides, a kids' splash zone, and lazy river under a heated indoor environment that runs year-round; the spa side runs as a multi-floor jjimjilbang with hot rooms, salt-loess steam rooms, ice rooms, sleeping areas, and a co-ed lounge with food. Combined day passes work as one-ticket access to both. For Seoul-area travelers staying in eastern Seoul, Park Habio is one of the strongest indoor weather-proof options for a half-day with kids — particularly in winter when outdoor parks shut and the heated pools and saunas line up cleanly.
