Tianliao District is famous for its world-renowned mudstone badlands. This spectacular type of landscape can be found in Tainan's Longci and Zuojhen districts and Kaohsiung's Neimen, Yanchao, and Tianliao districts. Similar features can also be seen in Taitung County's Liji as well as Hengchun Township, near Kenting in Pingtung County. But none of these places can compete with the magnificence of Tianliao.
