Journey to the historically significant Pac Bo Relic Site, located near the Chinese border north of Cao Bang City. This area holds immense importance in Vietnamese history as the place where Ho Chi Minh returned to Vietnam in 1941 after 30 years abroad and began organizing the revolution.

Explore Pac Bo Cave (Coc Bo Cave), Ho Chi Minh's modest living quarters, walk alongside the crystal-clear Lenin Stream, see the Karl Marx Peak he named, and visit the Ho Chi Minh Museum and Temple within the complex. It's a deeply revered site offering both historical insight and beautiful scenery.
