Su Tie Mountain National Park is the largest mountain in Chiang Mai. It has an elevation of more than 1200 meters. It contains Puping Palace, Su Tie Temple, Huaijiao Waterfall, Monument and Observatory. It can drive up the mountain and reach Beishan Miao Village. In fact, the air on Su Tie Mountain Main Road is not very good because there are too many cars. The whole Chiang Mai can be overlooked on Mount Su Tie, which is especially suitable for sunset in the evening.
