The Four Heavenly Kings include Sitianwang Mountain, Qingyuan Mountain, Dubi Mountain and Zhiniao Mountain. They surround and guard the Shuisheliao and Jiaoliping area and are therefore also called the Four Season Peace Mountains. The trail only runs around Sitianwang Mountain where the Ali Mountain Forest Railway passes by the mountainside. Along a small creek, the trail leads up to Anbu through a moso bamboo forest. On the way, visitors can see the Ali Mountain Forest Railway, forests, mountains in the distance and seas of clouds.
