On your fifth day, take a day trip to the Pac Bo historical site, located in Cao Bang province, about 2 hours away from Thai Nguyen. This site holds great significance in Vietnam's history as it was the place where President Ho Chi Minh returned to Vietnam after 30 years abroad. Explore the various landmarks, including the Coc Bo Cave and the Lenin Stream, and learn about the revolutionary activities that took place here. Take in the beautiful natural surroundings and enjoy a picnic lunch by the stream.
