The Valley of Gangala is a subtropical forest with rich nature that was created by the collapse of a limestone cave until hundreds of thousands of years ago. It is a relatively new sightseeing spot that opened in 2008, including the ruins of a dwelling and an estimated 150-year-old “Uhushu Gajumaru” tree.
