Travel to Vietnam's symbolic northernmost point by visiting the Lung Cu Flag Tower. Standing atop Rong Mountain (Dragon Mountain), this impressive tower flies a giant Vietnamese flag and offers panoramic views across the surrounding countryside, terraced fields, ethnic villages, and into neighbouring China on clear days.

Reaching the tower base involves climbing several hundred steps. The journey to Lung Cu itself, through scenic landscapes, and the patriotic significance of the site make it a popular and rewarding destination on the Ha Giang Loop.
