Introduction to Tiantai Mountain: The Tiantai Mountain Cave Geopark is located on Eagle Rock beside the Biba Highway in Linfeng Township. It is the longest cave in Yunnan Province. In front of the cave gate, the clear Linfeng River slowly flows westward and flows into Baishui River. Surrounded by pristine scenery, you feel comfortable. There are halls in each cave, and the landscape is strange and mysterious. It has the characteristics of "grandness, beauty, wonder, and diversity", forming a pattern of caves in the cave, mountains in the cave, forests in the cave, and sky in the cave.
