If you're wondering whether it is worth visiting this eco museum, if u don't know korean, its not worth it. Everything was in Korean and only scientific names in English.

Having said that, the staff tried their best to explain to me in Korean, and brought me around the museum. Later on one young staff came and helped to translate (^_^;)

Inside u learn about the animals and insects in the river area, there was a dark room where u can see fireflies. a few fish tanks and a pool where u can dip your hands and fishes will eat your dead skin.
