15,000 won to get into the park which allows you to get into the cave. Park has lots of flowers and tropical plants. Bonsai area and Korean traditional housing area. Honestly, the park itself isn’t that cool. But the caves alone made it worth it. 3 caves. Takes a couple minutes to walk through each one. They’re cold and have water dripping from ceiling. Lighting inside and good signs explaining different points of interest. Recommend caves.
