  • A must go place if you wanna enjoy the pool during winter. Visited last week but enjoyed a lot without worrying much about the cold. They also have nice restaurants, hot spring, and a walking course for a stroll.
  • Yunessun Hot Springs theme park was EVERYTHING! Wine bath, coffee bath, sake bath, green tea bath, black tea bath, natural hot spring water slide, fish bath, and more! Heaven is a place on Earth y'all, and I went there. I didn't even know karaoke was an option until I read some other reviews. I LOVED this place. You can't go if you've got tattoos, but I wore a modesty bathing suit in the public areas without any problems.
