Eighteen Arhats Mountain is a nature reserve on the east bank of the Laonong River in Liugui District, Kaohsiung, known for its striking rock pillars formed by differential erosion of Liugui conglomerate, standing alongside the Laonong River Gorge as Liugui's most iconic natural landscape.
Eighteen Arhats Mountain is composed mainly of Liugui conglomerate formed after the mid-Pleistocene, not sandstone as sometimes described; the area features U-shaped valleys, gorges, and meanders. The Forestry and Nature Conservation Agency has designated it the 'Eighteen Arhats Mountain Nature Reserve' under the Forestry Act, covering 193.01 hectares.
Highlights of Liugui Laonong River Gorge
The Laonong River originates in the southern section of the Central Mountain Range; as it passes through Liugui, it incises a deep valley with a gravelly riverbed and water that ranges in color from blue-green to turbid brown depending on the season. Liugui Bridge is a key vantage point for taking in a full panorama of the gorge — from the bridge you can look down on river meanders and the steep vegetated slopes on both banks. Eighteen Arhats Mountain stands on the east bank of the gorge, where an impressive array of sandstone pillars lines the old Provincial Highway 27A corridor.
The Shisabajhoshu Nature Reserve has a trail system offering close-up views of the texture and color of the eroded sandstone pillars. Liugui has a long history of hot springs; hot spring hotels line the Laonong River banks, making a soak a natural addition to the itinerary. During the dry season (November through April) the riverbed is exposed, making geological features easier to read; during the high-water season the water volume is greater but the gorge appears even more dramatic.
