Yangmingshan National Park - Lengshuikeng Introduction
Lengshuikeng is located in a tranquil valley between Qixing Mountain and Qigu Mountain. This area was once a volcanic crater, and over time, erosion and human cultivation have softened its appearance, leaving only a gentle outline of a shallow depression. Geologically, it is mainly composed of tuff and andesite, and the rocks near the spring have been altered by geothermal processes, often becoming clay-like, which bears witness to the historical volcanic activity. The temperature of the spring water at Lengshuikeng is approximately 40 degrees Celsius, which is much lower than that of other hot spring areas, thus earning its name. It is also the only sedimentary sulfur mine in Taiwan, and the mineral-rich spring water appears a dreamy milky white, earning it the nickname "Milk Lake." The hot springs here are formed by the indirect heating of underground water and feature two unique spring types: neutral bicarbonate springs and weakly acidic sulfate springs. In addition to enjoying the hot springs, visitors can stroll to the beautiful Jiansi Waterfall or explore the serene Dream Lake Ecological Protection Area. In this fertile environment, you might unexpectedly encounter natural friends, such as the noisy Long-footed Red Frog, the elegant Huosheng Frog whose calls resemble bird songs, or the plain-looking Pangu Toad covered in warts. Occasionally, you may also catch a glimpse of snakes and reptiles. While ensuring your own safety, please treat these lovely residents gently, observing quietly and not disturbing their lives.
