태백산맥
As elsewhere in the Yeongnam region, the landscape is very lumpy, with many craggy hills and low mountains. The highest mountain in Miryang is Gajisan (), which stands on the northern border. Other high peaks along the border include Hwaaksan and Cheonhwangsan (also called Jaeyaksan). These peaks are part of the Yeongnam Alps, a branch of the Taebaek Mountains.
