I’m a local of Benxi. Just tell you that the ticket is 187 Chinese yuan. There are no direct buses from Benxi Railway Station to the Water Cave. You can take the express at Dongfen Bus Station to go there. The bus fare is about 9 yuan. The trip costs less than 40 minutes. If you want to go to the Water Cave by taxi, the taxi fare is more than 100 yuan. It’s a little expensive. So, I suggest you go there by express. Welcome to Benxi!
