Ha Giang is one of the highest towns of Vietnam and has a quintessential view of mountainous Vietnam and China, surrounded by sharp hills. Lung Cu peak at the height 1600m to 1800m compared to sea level, was considered to be the rooftops of Vietnam. Travelers have to overcome the peak of Ma Pi Leng. On beautiful days, its pass seems to collect all the beauty of nature, with the windy hill sides, the eyes spread to horizon.
