Designed for one day, this route could be the first choice for visitors to experience Cao Bang. From the City heading north, they would be surprised to find themselves among vast, flat paddy rice fields like those in the deltas, together with traditional craft villages and local dishes. Besides geosites such as the well-known Cao Bang Tien Yen Fault, the Keo Yen young karst landscape, the Lung Luong Ammonite fossils, this route is full with historic monuments such as the Ban Phu Citadel, the Na Lu Citadel-King Le Temple, Nung Tri Cao Temple, Kim Dong Tomb, Nguom Boc Cave, and in particular the Pac Bo Special National Monument, which records President Ho Chi Minh's revolutionary activities during 1941-1945.
