Only 150 metres from Cigu Salt Mountain was the Salt Museum, which claimed to have a complete collection of books and cultural relics pertaining to the salt industry in Taiwan.
Unless you speak Taiwanese Mandarin, my advice is don’t waste $T130 to visit this museum because there was very little in English. There wasn’t even a pamphlet in English to help me interpret any of the displays.
I managed to decipher that there were five different kinds of salt that could be extracted — marine salt, saline lakes, rock salt (halite), salt flat and natural brine. Other than that, I could only look at displays but not gather their complete meaning.
