Longfeng Waterfall (中文版： 龍鳳瀑布) is a very interesting waterfall in the Zhanghu Scenic Area (樟湖篇）of Yunlin, Gukeng Township (雲林縣古坑鄉). Quite amazingly, riverbed is lined with thousands fossils of marine life from 3.5 million years ago. The hike is short and easy, with several smaller waterfalls along the way, and nice swimming holes.
The waterfall is quite tall, but you have to look at it from the front to see all of it. It looks deep, and nice for swimming. The water is the same beautiful turquoise as the rivers in the area.
Road 149甲 is broken on the west side of the waterfall. It can be hiked, but not driven. You can get to the top of it from that direction (萬年峽谷) but the road doesn't go all the way through to the bottom. You'll have to drive around from the east side, or hike an extra 2.5km.
