The 99 Peaks Trail (aka Jiujiufeng Forest Trail or 九十九峰) in Caotun Township of Nantou County is one of the most unique and beautiful places in Taiwan. It features extremely steep grassy hills that look like they are from a cartoon. This is due to the easily eroding sediment that they are made out of. Taiwan's torrential rains and earthquakes have sped up the erosion on these hills, making them especially steep and pointy, and creating what looks like 99 peaks on the horizon. From the trail one clearly see the jagged 99 peaks as well as beautiful views of Caotun and Nantou.
The 99 Peaks are built on the same sediment as Huoyanshan, with iron rich soil that was deposited and lifted up due to tectonic forces.
Discoloration due to laterization (leaching and oxidation due to heavy rain) of minerals in the sediment has made the rocks near the top of the mountain here orange-red.
Like Tianliao Moon World (田寮月世界) and Liji Badlands （利吉惡地）, 99 Peaks is considered a badland due to fast erosion.
99 Peaks, Huoyanshan (火炎山), and Shibaluohan Mountain (十八羅漢山) make up the three "Huoyanshan formations" in Taiwan.
The slopes here are very steep, and average from 60-80 degrees, making them impossible to cultivate. The entire mountain area is like a bunch of mini slot canyons.
At it's highest point, the 99 peaks are 779 meters above sea level, but were only 777 meters above sea level before the 921 earthquake.
After the 921 earthquake, much of the soil on the mountain eroded away due to shaking, and the hills were left bare. Shortly after, the area was declared a nature reserve. 21 years after the earthquake, the hills are now covered in grass and shrubs.
The trail doesn't go to the very top of the peaks, and if you venture further be careful because the cliffs are very steep on either side and erosion could happen at any time.
As of March 2020, Nantou County has purchased the land of 99 Peaks for 100 million NT, in hopes of cultivating it for tourism, such as hot air balloon rides. Let's hope it becomes a major tourist destination!
