Stand at the symbolic northernmost point of Vietnam at the Lung Cu Flag Tower, a prominent landmark perched atop Rong Mountain (Dragon Mountain) within the Dong Van Karst Plateau Geopark. This towering monument, flying a large Vietnamese flag, represents national sovereignty and offers visitors sweeping panoramic views of the surrounding border region landscape.

Reaching the flag tower involves a climb up several hundred steps, but the effort is rewarded with breathtaking 360-degree vistas. Gaze out across the rolling hills, terraced fields cultivated by local ethnic communities (predominantly Lo Lo and Hmong), traditional villages dotting the landscape, and the distant border with China. The sheer scale of the scenery and the significance of the location create a powerful experience.

A visit to Lung Cu Flag Tower is a must-do for travelers on the Ha Giang Loop, offering not only incredible views and photo opportunities but also a moment to appreciate the cultural diversity and national symbolism of Vietnam's extreme north. Understanding the history and significance of the flag tower adds depth to the stunning visual experience from this important Ha Giang landmark.
