The Legend of Thien Canh Son Cave
The story of Thien Canh Son Cave is more about natural science than legend. The cave formed over millions of years through limestone erosion, where water slowly shaped the rock and created the stunning formations we see today.
The cave’s name has an interesting history. It was first called Hang Co (Grass Cave) because of its location on Hon Co Island. Later, to better capture its magical beauty, it was renamed Thien Canh Son, meaning “the mountain with the view of fairyland.”
Local guides love to point out specific formations in the cave, comparing them to familiar objects. You might see shapes that look like baby elephants, lotus flowers, or even groups of hamsters. While it takes some imagination to spot these shapes, it adds fun to the cave experience.
