Jasujeongdonggul Nara

Jasujeongdonggul Nara in Ulju, Ulsan is a theme park where visitors walk through a cave and ride a boat. The cave stays cold enough inside that it feels chilly even in midsummer, and the boat ride follows. The cave has enough space inside to sit and rest, and it can be toured with children. During the summer holiday season, crowds can push the boat wait past one hour.
