Tongil Water Park in Goyang is a water play area that runs a swimmable pool and bungalows with cooking facilities. It has an adult pool 1.2 to 1.5 meters deep, a 50-meter rail, and a children's pool slide, and you can grill meat at the bungalows. On weekends, good spots are taken by around 7 a.m., with lines forming from early morning. During peak season it is crowded enough that swimming is difficult.
