Shuanglong Cave, Water-filled karst cave in Jinhua, China.

Shuanglong Cave is a water-filled karst cavern near Jinhua where visitors travel through flooded passages on flat boats due to the low clearance above the water. The cave features multiple chambers and stone formations created by water erosion over thousands of years.

Shuanglong Cave formed roughly 100 million years ago. The Shuanglong Scenic Area was rated 4A in 2007 and upgraded to 5A in 2024. Writer Ye Shengtao toured the cave and described it in his essay on Jinhua's two rock caves, later abridged as a primary-school textbook text.

The name Shuanglong, "Double Dragon", comes from two stalactites at the entrance that resemble dragon heads (long tou). The cave also holds old cliff inscriptions in its outer chamber, and the writer Ye Shengtao described a visit in his essay on Jinhua's two rock caves, later adapted into a primary-school textbook lesson.

Prepare for an unusual experience where you lie flat in boats to navigate tight, water-filled passages through the cave. Wear clothes you do not mind getting wet and be ready for a different kind of cave exploration.

The stone waterfall inside the cave is 8 m (26 ft) high. A separate feature, the Xianpu Cave waterfall in the scenic area, drops 73 m and is described in Chinese sources as the world's tallest cave waterfall. Shuanglong Cave also connects to Binghu Cave by stone steps.
