Chiayi's attractions are mostly of cultural and historical interest. Foremost among these is Lantan, which used to be called "foreigner's stockade".Bordered by mountains on one side and the sea on the other, Chiayi County is the only county in Taiwan with three major national scenic areas: Alishan National Scenic Area, Southwest Coast National Scenic Area, and Siraya National Scenic Area, each presenting a unique view of nature's wonders, from mountains to plains to ocean views. Alishan, located in the east part of the county by Taiwan's tallest peak, Yushan, is the homeland of the Tsou indigenous people.
