Located right beneath the Seongsan Bridge, the Mangwon Pool features a baby pool, a youth pool and an adult pool. All pools are separated according to depth, making it the ideal spot for families of diverse age groups. Located inside the baby pool, there’s also a mini fountain and a wooden deck that the whole family can lounge about on. The pools sit right by the river, so you’ve got a great view too.
