Here is a list of the most stunning caves in Vietnam compiled by news website Zing.vn.
1. Huong Tich Cave
Huong Tich Cave is at the center of Chua Huong (Perfume Pagoda), a vast complex of Buddhist temples and shrines built into the limestone Huong Tich mountains in Hanoi’s My Duc District, around 70 km southwest of the city center.
The mouth of the cave has the appearance of an open dragon’s mouth with Chinese characters carved in a wall at the mouth.

The characters translate into “first-grade cave of the Southern World” (Southern World refers to Vietnam) and the carving is dated to 1770. The words are attributed to the ruler of that time, King Trinh Sam.

2. Tam Coc - Bich Dong
Tam Coc-Bich Dong in the northern province of Ninh Binh is dubbed “the inland Ha Long Bay”.
