The 23 caves have been added to the system of local caves following a field survey at Ha Long and Bai Tu Long Bays in late 2015. Many of them are highly valued for scientific, archeological and tourism features.

According to Pham Dinh Huynh, Deputy Head of the management board, experts have temporarily named each cave, but the board is still working to find suitable names for the caves based on their outstanding values and characteristics in order to set up scientific profiles for management, exploitation and preservation.
