Observe volcanic landforms at Lengshuikeng

Source / Monochrome Editing Team

The hot spring here has a temperature of around 40°C, much lower than the over 90°C springs found in other areas of Yangmingshan. Additionally, due to the formation of a depression after a fault subsidence, it is called “Lengshuikeng” (Cold Water Pit).

This is the best geographical classroom for observing volcanic landforms. On the north side of the depression, you can still see thick smoke emerging from volcanic craters. At the same time, there are 24-hour free hot spring pools available here, with separate baths for men and women—don’t miss them.

Additionally, nearby attractions include:

◎ Qing Shan Suspension Bridge – The water beneath the bridge flows swiftly, with faint traces of early miners still visible. The yellowish-red rocks by the stream, affected by volcanic sulfur, display different hues.

◎ Cedar Forest Plank Walk – The cedar forest was replanted after the Retrocession Period, and now features well-built wooden walkways. Although it’s an uphill path, walking is not too strenuous, and the cedar shade makes the journey pleasant even in strong sunlight.

◎ Slag Lake – This area was once a dumping ground for sulfur mine waste. After the waste was cleared, it became a pool and began to be used for cultivating Taiwan water celery.

◎ Lengqing Trail – This trail avoids the busy Zhonghu War Preparedness Road. It passes through slag remnants, several small hills, cedar forests, and deciduous woods, leading directly to Qintian Gang Grassland. The trail is rich in plant ecology and includes an observation platform for enjoying the surrounding scenery. It’s a highly popular hiking route.

◎ Milk Lake – As a sedimentary basin for sulfur mines, the andesite bedrock at the bottom of the lake turns into white soil under the erosion of sulfur gases.
