Yangmingshan's original name was Caoshan (Grass Mountain in Mandarin), referring to the tall silvergrass that covers the highest slopes. Chiang Kai-shek renamed it Mount Yangming after his favorite Ming philosopher Wang Yang-ming (A.D. 1472-1529).

Lengshuikeng (冷水坑), contains Taiwan's sole bed of precipitated sulfur. Sulfurous fumes vented in the bed of this marshy lake turn the water murky. After gradually precipitating, the sulfur forms whitish-yellow or pale gray layers in the lake bed.

For the convenience of visitors who wish to wash and relax, there are two hot springs pools and one foot-soaking pool.
