Towering coastal cliffs are a regular feature of Taiwan's east. The most spectacular examples, known as the Qingshui Cliffs, extend 21km from Chondge, just north of where the Liwu River enters the sea, to the town of Heren. One classic location for cliff viewing is a little pullover park at Km176.4 on Hwy 9.
The cliffs are composed of durable marble and schist walls, which rise 200m to 1000m above sea level. They form the easternmost section of the Central Mountains, and reportedly are the oldest bit of rock in Taiwan.
